PC Unable to load world created in 2.0 experimental after saving in released version.

Version

2.0

Platform

Windows

I was able to load the save properly through out the experimental beta, and once properly in the released version. After that it is no longer loading and saying it reached the end of file:

The exit log does not appear to show anything different than other exits. I do have a manual backup of my saves folder from this morning a few hours before the release. Comparing the file sizes I do not see anything that seems exceptionally different size wise.

I can load in to the backup copy of the world from this morning, so this is not corruption related to an old save. If needed I can provide additional logs or save files if this helps troubleshoot the issue.

By chance did you complete or recently attempt a T5 POI? If so, what POI, quest type? Any other related information might help us narrow down the problem as well. I noticed part of your error message refers to "MinScript" which is a feature we use mostly in our upper tier POIs.

I am fairly sure it was a T4 POI, and it was the working stiff warehouse in the burnt forest. If I remember correctly, I made the backup right before horde night, and only did that POI.

Here is the log file from the last working save before it broke:

Mono path[0] = 'D:/SteamLibrary/steamapps/common/7 Days To Die/7DaysToDie_Data/M - Pastebin.com

Pastebin.com is the number one paste tool since 2002. Pastebin is a website where you can store text online for a set period of time.

My main base is just outside the new Corrrea Rockworx T5, but I have not attempted the POI yet. I probably flew over it though, not sure if that would have triggered anything.

Oh you have a backup? So you were able to roll back?

 

[smsldoo]

I do have a backup made right before the previous horde, and can roll back to that if recovering the save is not possible. I would lose several hours of game play, but if I have to use the backup it is not the end of the world.

I have copies of both the backup and the broken save and can provide them if that would help troubleshoot.

I've encountered the same issue, and I'm facing a problem with the main.ttw file, and I'm not sure what to do. I've created a new world and loaded the files from the save one by one, but I've discovered that the main.ttw file prevents the world from loading. Do you have any suggestions on how to resolve this? edited:The only thing that changed in my world is that I now have 1 day instead of 7. To do this, press F1 and type dm . Then, press ESCAPE and select the day that you had (if you remember)

 

[smsldoo]

Looking at the file it seems to primarily have zombie location data, but also sets the date (and I am sure other things). I restored that file from my backup and the load succeeded, but I was back at day 56. My location, inventory, and world are from when I last exited. I assume this file maintains the more dynamic, non world-gen, elements that are not directly tied to a player.

In my case, since I have a good backup, it is probably better to just revert that file, but likely is not a totally ideal solution for everyone.

I had this happen again a few days later. I am fairly sure I did not initialize any POI quests this time, and did not fly over Correa Rockworx, although I may have gotten close enough to activate it.

Here is the log from the last working play session:

Mono path[0] = 'D:/SteamLibrary/steamapps/common/7 Days To Die/7DaysToDie_Data/M - Pastebin.com

Pastebin.com is the number one paste tool since 2002. Pastebin is a website where you can store text online for a set period of time.

Here is the broken log:

I did look through the last working log, and the one before it and it seems like the entries related to SleeperVolume are basically the same. As I travel back and forth between my old and new bases, I am likely triggering the Rockworx POI. But I am not really seeing any new zombies, showing up under SleeperVolume at least.

Even though I can restore the main.ttw file, and temporarily resolve the issue, it does seem to be reoccurring. It is not really viable to keep resetting to that point in time. I am working on getting away from my current base near the POI, but that does not really solve the problem if the POI is going to just keep breaking things.

Is there a solution to this, such as killing off the zombies in that area, that would at least resolve the current issue?

I'm curious if you've made any progress with this. I just had the same error while poking around Rockworx and I'm not particularly interested in restarting my game after just having to restart my game to play 2.0. I too have backups I can go to, but again I'm not really interested in losing progress again. I am willing to load them for troubleshooting/information gathering if needed.

I can offer some more specific insight however. Rockworx is literally across the path from spawn point and the house I took over to start. I poked around in there very early knowing it was a bad idea. The first issue I noticed was the spawns were broken. I saw this going up the hill to the admin building which was my first path in. Things kept respawning almost instantly. The tower to the left as you enter that gate at the top of the hill was a literal vulture volcano. I poked around that area over a couple days as I wasn't sure if that was intended behavior. After seeing the mobs spawn stacking on top of each other, as in a dozen or more, I decided to move on from that for a while.

I came back a couple weeks later having saved and reloaded the game multiple times over that time period. When I cam back the spawns at the top had stopped and I cleared the area. I left for a day to go to another close POI to clear as the loot respawned.

My next foray was scooting around behind the entrance building intending to head down the road past the main gate. This the next spawn event and again the mobs just constantly respawned. This time I was tough enough to kill stuff more easily so I hung out and just kept killing as best I could. Eventually I got bored and went off to do other things. Again when I came back a few days later the spawns stopped.

This is where I believe it broke.

When I came back some days later. I went down the hatch/ladder by the cargo container down from the entrance building. When I went down I saw the locked door and turned to leave, but it unlocked and opened (Intended?). Creepy, but ok so I went into the mine area. Spawns trigged in the tunnel area with the carts that makes a loop. This was different as there seemed to be a lot, but I couldn't tell if these waves were as intended. I was however able to kill everything without leaving the area. However when I got into the back control room and moved into the next tunnel over with the breakroom I noticed some structure textures were just black. It was getting late and I didn't want to trigger anything at night so I left the way I came. On the way out I noticed more and more black textures on various walls/surfaces.

I assumed/hoped this was just a bug and decided to quit and make breakfast. Upon returning I now get the aforementioned error.

I apologize for the soliloquy, but I hoped outlining a more detailed experience with the POI may help pinpoint the problem as, from my experience at least, just entering the POI wasn't an issue, but appears to be something triggered during exploration.

We have a possible fix to prevent the issue from happening again and possible workaround if your on PC (e.g. restore from back up file). See post from Faatal below.

Linux Post in thread 'Game save corruption - EndOfStreamException'

Wednesday at 5:57 PM

Data in sleeper volumes in the main.ttw file is being corrupted when a count grows past 255. There is a main.ttw.bak file that you could use to replace main.ttw.

Allan and I reproduced the issue today and I have a fix for it that will be in 2.1.
"Fixed save would be corrupted if you repeatedly went near the same active scripted sleeper volume and then left the area".

I was able to pull a noncorrupted file from a couple hours before the error started and the game did load. It looks like parts of the game are still in my future, but I am assuming/hoping things will sync backup as I move through the time periods I already played through as far as POI status. Regardless this is much better that restarting.

Thanks for the follow-up.
