I used that fix. Was quite tricky given that I normally have autosave disabled so save disk space.
Anyway, it didn't work. I mean, it did... for a while... but the error returned!!
Do I have to use it everytime I want to contact that civ?
It was really bad timing for a crash aswell, right in the middle of a war and my troops were awsome. I doubt I'll be able to repeat that peformance
