Game breaks and doesn't allow me to click "Next turn". Am on turn 42 this time, so I'm not that far in. :<
Ah, that'll be a crash, sorry. There's a game log file (in varying places depending on OS) that should have the details, if you can send it to me (discord works well, but whatever's fine).
The game should have been doing autosaves which can be accessed via the saves menu, though you'll lose some progress.
