I've been getting a lot more crashes, too. Always between turns. It's the program itself causing the problem. I've got it happening on multiple machines, exactly the same style of crashing on each one, and I know other people having the same problem. I think it's caused by the way they're doing multi-core processing, in that they have as much happening at once as possible, and I think certain events conflict with each other and the program doesn't know how to handle it. That's my best hypothesis, anyway. FE's always had between-turn crashing, and they keep putting out patch notes that claim it's fixed but it never is.
