Ok I'm back after fixing the error messages, when loading a game that would crash before it keeps crashing and when I started a new campaign the same CTD happens as before around turn 58 this time.
There were no new (error) messages in the log, so I tried the more extensive log. However this also doesn't show an error that would cause the CTD I think. I put the log in the attachment.
Thanks again for your time, any idea how I could continue?
