Possible Bug - Phantom Blocks - I Believe It's a Long-Known Problem

if there were a good / agreed upon method to “try to replicate this” that would be acceptable (like what map to load, what to do/how far to go/visit a certain POi to visit either manually or using debug menu commands) I’d be willing to try it out a bunch to see if I can replicate it. I know it sounds weird but usually when it happens I haven’t seen a pattern to “what I’ve been doing In  game” and it occurring.


I can post my Nitro map where the issue has occurred consistently on A19.4 b7 with instructions for replicating and my complete system specs.

 
I can support this.  My previos computer (>10 years old) had this issue all the time; my new computer haven’t had this issue at all.


I get the issue on a new 'gaming' laptop (i7-10xxx, RTX 2060), but it's rare and I'm using Compopack POIs so my experience is not valid for bug reporting even if I could replicate it.

I should have also noted on my post that I play strictly vanilla.  No mods, no custom POIs, using the games RWG.  Though, I did have the phantom block issue on my old computer under the same vanilla conditions.

 
Yes please

Replication steps:

1) Start a new game, with any settings

2) Spawn into the world and make your way to the city (roughly in map center)

3) Either spend an extended period in a POI on the edge of the city (+1 hour) then return to the middle of the city (high rise or trader area), OR -

4) If phantom blocks aren't appearing, return to POI on edge of city, leave the game and reload / reconnect and then travel to the middle of the city

Some Notes:

- As stated before, phantom blocks tend to appear more frequently on older POIs from pre-A18 builds of the game, but I've also seen them on newer prefabs

- I have seen this bug in singleplayer, a private friends-only game, and in a dedi server all with the same map

- The bug persists in vanilla and modded 7DTD

- When the phantom blocks appear, if you quit and reload (sometimes restart the whole game), they vanish and will start appearing in chunks other than the one your PC loads into on entry

Are you still running that map and can you replicate the problem at will? If so, can you grab a couple of POI names using F3? I'm keen to understand how pre-A18 POIs are showing up on the map if you haven't installed them in /prefabs. Knowing the names of the borked POIs would help suss that out.

Or do you mean A19 POIs which have carried through the alphas from before A18? Maybe I misunderstand.

Definitely the former.  There's a couple prefabs in particular I recognize from some of the very early builds of the game - one looks like a ruined downtown bank or something.  Others include ruined multi-story buildings.  I'll take some screencaps and try to figure out their names.

 
Here's some screencaps.  I'm still looking into the specific prefab names:

Notice the phantom blocks present here, but not in the newer POI across the street -

See the following screencaps for additional older POIs.  Curiously, the Dishong Tower highrise was fine, while the pharmacy high rise had phantom blocks.  Meanwhile, nearly all the older POIs consistently had phantom blocks.

Excellent! I see what you mean now, sorry for misunderstanding before. These are "old" POIs in the sense that they've been in the game a long time, but they are still valid A19-installed POIs. Perhaps not optimized in some way.

You can get the POI name from the F3 display if you are within the bounds of the POI. So just move closer and you'll see the name right next to the Biome entry.

Edit: it's interesting that you seem (if I'm interpreting the pictures correctly) to get a couple of different phantom block textures showing up. As far as I can remember, we always see only the black marble texture, except in trash piles and shopping carts. When the bug hits our map, we will see weird checkerboard blocks in the middle of trashpiles and carts. Each face is 2x2 textures, with the black marble and "plywood" dark & light grey cement texture alternating. I think I have a picture of it around here somewhere. BRB

Hi i just made this account because i have some important info I didn't see in the thread here, I'm having this issue seemingly EVERYWHERE i look, i play a pure vanilla game as the host of a friends only server that has had only 2 people play the game,  My issues have been seen in effectively every POI in a normal town/city spawn, there are no larger multistory buildings except for one and some destroyed building that was fairly small and had a single roofless room with a gun-safe in it.
These areas i know the descriptions of, that had this issue infesting them, are:
A gass'n'pass gas station, a diner with a large sign on the top of it and two outdoor eating areas, the shotgun messiah Factory, a regular house two feet away from a trader, a high school, a Crack a book building, to be specific the one i saw had a small hold out with a couple of crates on the roof, Notably I've been running into a lot of extra phantoms, not just the marble block seen in doorways and other areas, or the checkerboard block in the trash, there are also:
Trapdoors that are melded with a wooden plate, the entire Shotgun messiah is encompassed in a one way black glitched zone, meaning only the outside of the blocks making up the poi, the trash and shopping carts are also glitched with this pitch black box. There are tons of examples of this showing up in my world, and its solely vanilla RWG, to be clear they can happen in seemingly any area with multiple POIS but nothing seems to be safe from the glitch in my instance.  I will get screenshots soon. also I'm not running NVIDIA in the slightest, i swapped out for a decently powerful Radeon Graphics Card. Which can run ultra without issue seemingly,  Save of course, this error, which happened on Default graphics settings as well.

Logs?

Hardware information?

Any useful information?

Not to offend, but this doesn't add any really useful information.  We have way too many posts like this already. We need hard data.

I'm not exactly good with figuring out hardware info, but i believe i can get the logs if i know where to find it, the main reason i wanted to post was because i was noticing several things that didn't match other people's posts, such as the one way black texture issue with the Shotgun Messiah factory and most people here having the issues with mostly GeForce graphics cards, I'm not exactly super technical i just wanted to provide what id seen.
And don't worry I didn't take offense, i mostly just have no real technical info atm. I can prolly try to use that F3 thing someone mentioned to find more poi names and screenshots with it but that will take a bit.

Instructions are Pinned right here in this section. Please take the time to get the details.

 
Ok so i have some Screenshots of the buildings however the glitch has vanished from all of them thanks to a game quit in order to change the settings to allow for creative tools so i could use fly mode without danger. but all of the locations are screen capped, i cant quite figure out how to put them into the post though.

 
Instructions are Pinned right here in this section. Please take the time to get the details.
Here are the Listed POI Names for each one i noticed the glitches affecting. i hope this helps even a little
POI: house_old_pyramid_02.545
POI: house_old_modular_07.537

The first two are right next to a trader settlement and only exhibited the usual issues, marble blocks in doors and windows and glitched trash piles.

POI: buisiness_old_05.321
POI: buisiness _old_06.318 (this one looked like a school, it had a sign naming it Special Tottz)
POI: fastfood_03.307 (Huge sign named Bezerker Bills if that helps)
POI: gas_station2.305 
POI: store_book_01.317 (Crack a Book)
POI: factory_lg_02.334 (This is the only POI that had the black zone glitch)

POI: store_hardware_02.291 (I wasnt here long but i noticed the same issues as most of the other stores)

Also i should add, something i noticed is that the outer block faces of most of these POI's were flickering as if there were phantom blocks trying to render over them or something.

The gas station, the fast food place, and the book store all had phantom blocks everywhere all being the dark marble block, all three also had the trapdoor phantom block as well. if i can get anymore stuff to help i will but hopefully this gives some more technical insight.

I tried these steps using the Warhawk 4k map and couldn't reproduce.

Ultra settings

GTX 1060 6Bb Driver version 461.09

I5 3550, 20 Gb ram, sata ssd.

After step 3 when the phantoms were not appearing, I did step 4 five times and still didn't repro.

I also tried flying around the map in god mode for about 8 in game hours which also did nothing.

 
Okay so recently I've reproduced stuck imposter blocks but it was during an insane amount of exit/enter/swap POI/ go into playtesting that went on for like 2 or 3 hours, not something in normal gameplay. Still a repro but I'd like to narrow it down a bit in the "normal" use cases. One thing I'd like from you all whom are able to reproduce it is:

Are you using a HDD, SSD, or an M.2 drive?

Very specifically, how much ram do you have (simply "8GB DDR4" hasn't provided results in this case), how many sticks, and the specific model of it with the main timings? https://www.cpuid.com/downloads/cpu-z/cpu-z_1.96-en.exe

that program will help, if you click the memory tab and take a screenshot of what's in there that would be awesome. Reason why I'm asking mainly is I can tailor my system (maybe, if you have DDR4 ram I can).

My 7DTD is installed on a 1TB Western Digital HDD.  RAM is Corsair Vengeance, 4 x 8GB DDR4 - 3200MHz base core clock.

EDIT: Also sorry that my repro steps didn't work straight away.  Seems the way the bug manifests can differ for separate people.  But I've had friends playing the Warhawk map with all different specs complain about the same issue.  I'll collect system info from them (9 other people) to give you guys a broader data pool.

Oh don't be sorry thanks for the information. Yeah you are right about the bug being weird for different people. I think that's a first I've seen, someone having fast/strong ram and 32 gb at that, we're slightly different but mostly equal in that department. But I do have a HDD I can use to test, normally I'm on my m.2 or a regular SSD.

One common thing is the HDD, see if your friends are using HDD and if they are using an SSD/M.2 instead, please gather ram info from them. Unless you/they don't mind giving ram info, can't hurt! The last time I tested for it in a real game (not just testing random crap like in the repro i mentioned) I had 2 - 3 copies of the game running while running a membench in the background (among other stuff) to keep my ram as full as possible but didn't get any to stick. Pretty much had 100% cpu and ram utilization. But I'll make a new test using a HDD sometime soon.
