[0.12.8] Dedicated server crash after desync

[daniel34]

Since I've set up my server in July I've never seen this crash message, so I'm posting it here. It occured after restarting the server with an autosave after a known mod related crash happened. The server/players started to desync sometime after and a desync-loop happened, where the game always desynced shortly after the players rejoined. Then the server crashed with this error:

The server is working again now without desyncs after I restarted it with the latest autosave.

You didn't put the whole log there, neither the save file and mod folder, so there is no chance to reproduce it.

Are you sure it isn't some faulty mod doing that?

[daniel34]

Sorry for not providing the save file and mods (as mod, I should know better ). I tried to reproduce it on a local server + 2 clients with a later save because autosave overwrote the save in question, but no luck.
Might be mod related, as we've had problems with these before.
I'm moving this to resolved.
