[Rseding91] [0.17.62] Crash on save: "Count of indexed targeters doesn't match count of saved targetables"

Post by Muppet9010 » Mon Aug 05, 2019 4:45 pm

When an MP server running "_autosave2" attempts to make the next auto save the server crashes with the attached errors.
The autosave interval is 11 minutes.

I have tried loading the server again from a copy of "_autosave2" and the game crashed with the same error on first autosave attempt.

However, in SP loading the save it doesn't error saving or loading.

Thanks for the report. I looked over the code and can't see any way that could happen without some corruption issue through a mod or on the server.

I tried to reproduce the crash locally but it just desynced after a few minutes of waiting doing nothing. So, I would look at your mods and figure out the desync first. It happened right when an alarm started playing.

Further to the discord discussion earlier.

I've just tried running this save on a headless windows install of 0.17.62 on a secondary pc in my house. I can reproduce the server crash when the autosave runs after I connect to the server with my main pc.
The attached save should skip basically all of the waiting of the previous save. It seems to crash the game after the mod Warptorio has done its warp action as if you force a save before the game is happy.
  1. Run headless server on the attached save "JD server crash pre.zip".
  2. Join the game with a client
  3. Once caught up the text at top of screen "Auto-Warp In" should be 60+ minutes. If not wait for it to count down to 0 and reset back to 70~ minutes.
  4. Trigger a server side save with "/server-save"
  5. The server should die with the error.

Ok, I figured it out. The time-travel logging was actually useful in seeing that it was always deleting a surface right before it would crash. The reproduction steps where: make a reference to a lua chart tag on a surface, delete the surface, and in the same tick auto-save happens.

It's now fixed for the next version of 0.17.
