Crash on end turn/Continue Campaign

When I tried to end a turn playing as the Romans I got a crash at 262BC, I have had other crashes prior to this but this one broke the campaign. I can't play that campaign at all, it errors on loading.
In general, this version is EXTREMELY unstable compared to 2.2B

You need to switch the logging method back to trace, when providing logs in this forum, that log tells me nothing more than that there is a crash.

Do you have autosave enabled? That corrupts saved games.
