Hello everyone,

New guy here, tried reading the pinned post for this issue I have but either I'm not looking well or probably on it's way being fixed or something. Anyhoo, love the game, have it both on the PC and PS4 (PC player now), well my issue is that sometimes when I move my vehicles like the truck or gyrocopter to explore the game, I come back and there's another copy of w/e vehicle I left in it's original spot. Not sure what is going on but recently I had filled my truck with loot to sell to the trader, went for a quest with another vehicle and I come back to check on my truck and everything in it is gone. Thought ok, drive it away from my base, might be a glitch or something, nope, nothing in it tho when I check it's inventory, i can see my items for a split second and its all empty. Now I go back to my base and I find another truck where my orignal truck was parked and I'm like what the hell...I check it's inventory and it has all my items that disappeared in my orginal truck...so yeah, I dunno. Don't need another truck or gyrocopter, not sure what is triggering a copy of them when I leave my base that's not on POI but on a clean ground where I have built a small fort on some hill and just adding stuff as I go along with the game. I have over 100 hours playing the game and this has happened twice already. Known issue or something new?

p.s. love this game on pc, so much fun. 😁

This is where your output logs are at. I haven't seen this yet in SP and only on dedicated servers; were you playing solo? Do get back and throw some output logs up. Sorry it's happening

 
Playing on own dedicated server and this happens -alot-.

I am now a fleet admiral commanding 16 Bikes, 12 Minibikes, 17 Gyrocopters, 2 Motorcycles and 7 4x4's

I only crafted one of each.

Seems like the game keeps an array of each vehicle and what it was carrying when the vehiclemanager saved.

(Which is double annoying since the game's backup on players are awful)

 
Hi there,

I have a slightly different issue. After exiting and restarting my savegame, I lost all vehicles.

Near the end of the log of the first game it says:

Further up in the log the line

At the beginning of the log of the session that atrted without vehicle is reads:

Any idea why this happened?

 
I'm seeing the same issues -- disappearing inventories that reappear later and duplicated vehicles -- on 19.4 (b3) via the experimental branch. I'm playing on the Not-A-Gamer Gaming long term server.

Sometimes I can just wander a ways away and come back and get a different inventory, such as the current one or one that was current a day ago. Sometimes I come back to an empty inventory, or maybe a super-quick glimpse of items in the inventory and then it looks empty.

I had one misadventure when I died and when I arrived at my bedroll (at my base) the vehicle I had driven there was back at base with me. So I drove it back to collect my backpack and the vehicle I had parked there was gone. So, I figured there was some bug that transported my vehicle back with me. Alas, a few real life days later and I noticed a copy of the vehicle where I died was sitting there.

Another observation. Start with a vehicle showing its inventory. Remove the inventory. Now take the empty vehicle into your inventory. I get both a vehicle in my inventory and the vehicle itself still sitting where it was parked and it is holding a copy of the starting inventory. Everything duplicated.

The most annoying, frustrating thing is when you load up a vehicle's inventory to go work on a project and then that inventory disappears for days.

Most likely causes: Bad infernet connection and/or bad FPS at your side or the servers side.

Vehicles that reappear at the place where one started driving is a common phenomenon. We get that too from time to time, often when one of the players gets disconnected from the server.

The game is forgetting where multiple vehicles are, deleting them completely from the game, forgetting locks/passcodes and delting storages from the game as well.
Since A19.4, server has also been randomly disconnecting players who are then able to rejoin immediately. I as an admin via LAN connection to my server was once disconnected. I just bought all-new hardware for an unrelated problem and highly doubt its the new hardware. I think this bug might be a little more obnoxious than you think, especially in PVE situations with multiple vehicles.

At least in me and my gamers experiences. There are also quite a few random bug reports and threads on this topic now over the past 2 months.

I had to disable EAC and Sparks to get 2 players with meh connections playing. (220 ping, 50mb down) connecting to server with 100mb down/6mbup. Pings via CMD and speedtests showed stable connections with no packet loss.
"Server timeout." Yet no timeout is actually taking place on hardware end.

Possibly.

In our 4 player co op game it is always the same one player that gets disconnected frequently. One difference is his provider which looks like it could be the reason. Any other hypothesis?

We also have locks being forgotten, again he has it all the time but it seems we do too sometimes. Which is something that points more in the direction of a universal bug instead of one induced by FPS or very bad connection or latency

Its happened to 3 players across 3 countries for us.
Ima go ahead and humor your hypothesis tho and ive setup my QoS for 7d2d on my PC and ill do some more testing over the next couple days and see if its a networking sensitivity problem or not. I really dont think thats the problem but just to help rule it out.
Will update this post in idk, 24, 48hours once my gamers have a chance to help test.

In the logs and speedtests ive done when the DC happened/as close as humanly possible, the networks have shown 0% packet loss, even on the 'poorer' network connections.
However, in 7d2d it says "High packet loss, disconnecting client"
Due to this reading, ive sat and watched multiple tests carried out over 15m span on the afflicted persons network only to see no more than 1% packet loss or less over the duration.
It could be that the networking on 7d2d is just being way, way too touchy on what it considers "Excessive packet loss" and is terminating its connection. Could even be issue with the steam API- I know a recent steam patch was to quote "Fix p2p networking issues in steam api" so... This could be a double problem thats compounding a minor issue in 7d2d.

PS: Ive gained stability for the poor connection players by disabling EAC and Sparks via 7d2d game launcher on the 'poor connection' PCs which has at least made the game playable for them folks.

 
If it is a problem with the steam API, if we do as the devs say to and disable steam networking in the server configs, it should bypass using the steam api- but your buddies will be forced to join the game via server list. Might be worth a try.

That doesn't say much. It could be a setting some providers use for their routing or traffic control, it could be the internet router brand given out to customers of the provider. In both cases it could happen in any country.

Its still happening. DCs because the server feels there 'is too much packet loss.'
I had 7d2d QoS via port at highest prio. Still happened to people at the same timeframes.
Resulting packet loss tests confirmed server was experiencing 0% packet loss over 15m interval.
This bug has only happened since the most recent stable release. (At least for us)

This issue also happens with a buddy who lives one timezone over from me, based in the USA and we ping off eachother at about 40ms. He has a stable PC with good, reliable internet and he still experiences the same issues. I even DC from my own server occasionally due to 'packet loss' yet, again, packet loss detector says 0% loss.

Strangely our "problem magnet" player had that problem for previous alphas even. It might mean his and your problem are not from the same cause, or the bug has multiple or complicated conditions to activate.

I would say you should make a bug report, but I can't give you much hope this bug will be found soon, it seems difficult to replicate. But someone has to start the bug hunt. The more people report the bug the easier it is to find a link between them

For what it is worth, we had that issue occuring for several alphas, too.

But vehicles replicating started in A19 only, as far as I can tell ;)

It was always some player that had a notibly bad connection on that particular evening, resulting in disconnects at times.

Vehicles disappearing has not always been happening on disconnect, though: it did on occasion, and sometimes it did not, sometimes it happened out of the blue.

Also, steamnetworking enabled or disabled made no difference.

Never had there been any server or client log entries to the likes off "High packet loss, disconnecting client" which makes a bug report close to pointless.

I will test with yet another server with hopefully better carrier peering shortly to gain more insight.

I know there are no easy leads, but like Sherlock Holmes said:

Holmes: “To the curious incident of the dog in the night-time.”

Gregory: “The dog did nothing in the night-time.”

Holmes: “That was the curious incident.”

 
I play solo-local in a random world (alpha 19.6(b8)), and my 4x4's inventory keeps changing on me. At first I thought I was losing stuff, or that this or that item was destroyed in X or Y stability related collapse, but no, the 4x4 is physically changing its inventory. Gotta say, getting gaslit by a jeep is kind of annoying. 

I have noticed that logging in and out triggers the inventory to change. Its like there is something wrong in the code that handles the repop of chunks/refresh of chunks, loading save data or all of the above. I have had weird issues on my highway I am carving westward from my easterly desert base, where the vehicle will be parked where land once was, and I will walk away to work on digging through a house or whatever, and then when I come back, the terrain will come back for long enough to throw the vehicle like a toy and nuke a quarter of its health. 

I think the game is keeping some kind of manifest of items/objects (talking entities and etc, not the inventories themselves) based on LOD related load-ins and somehow things get crossed. I suspect that the different inventories I am seeing are each related to different instances of my 4x4 that some part of the code sees as two different vehicles, even though they are the exact same elsewhere.

Honestly, im surprised this game runs this well as a unity title as is, and when i collapsed several chunks to bedrock, the game didn't crash. It did tank frames when I collapsed an apartment building, but I think that was more the screamers spawning in. I bring up the apartment collapse, as it seems that if you move far enough away while the building is collapsing, bits of the building will seem to glitch out into a floating state. I think the physics loop is suspended for blocks when you move far enough away, and doesn't re-evaluate newly loaded bits. instead it seems to default to the premade mesh/world state for large distances >32m and then loads in modified terrain when within that distance... the issue is probably related to that change over, and how vehicles persist in some form outside of that 32m distance. 

so yeah, pretty sure all of that and yall's issues are related to what is happening with vehicles, and that it is all related to how chunks update. As reloading the game refreshes chunks, moving far enough away from a space refreshes the chunks, loading in from being kicked refreshes them and etc.

 
If you want help please post this as a new thread instead of highjacking a practically mummified thread with a totally different issue. Also please read the sticky thread that tells you how to post a logfile

I have not seen the reshuffle of the inventory and the throwing of the vehicle in my games and no other players have reported this
