I have a long-term save going. It always crashes when processing past 00:00 of January 8, 2032, either by continuing or holidaying.
I am running FM version 18.104.22.1686437 under Linux using Proton 4.2-3. I have no access to a Windows machine to test whether it's a Proton thing. But I'm more inclined to think it's an editor data issue, as I had to use one to manage in Azerbaijan. I have not used the in-game editor. I have custom graphics loaded, but it does not seem to make a difference.
I have already tried verifying the game files and deleting cache+preferences. Same result.
I have uploaded my save game and crash dump to your owncloud under the names "sabail.fm" and "sabail.dmp". The save file is saved just before the crash point: you just have to press continue and it will crash after a while.
Thanks in advance for looking into it.
