Played an online game with a friend. He's the server, I'm the client.
The game is SA with mods.
When trying to upgrade belts using the upgrade planner (on the quick access panel) the game crashes.
When upgrading belts manually everything is ok.

EDIT1: When reconnecting to the game after crash, the belts are already upgraded.

EDIT2: Added actual log and dump with error. After some investigation, I found out that it's the TLBE mod that's to blame. Apparently, saving snapshots for timelapse breaks synchronization (or something like that). Without the TLBE mod there is no error.

Thanks for the report however that log does not show any crash in it?

Oh, wrong log was attached.
Fixed now. And some info added.

What steps do I need to do to reproduce the crash?

Try to upgrade Yellow belts to Red with Upgrade planner from Shortcut bar below.

And you can reproduce the crash 100% of the time?

Ah, it was the "while a peer in multiplayer" that I was missing. I reproduced it and it's now fixed for the next release.
