Is there some way to get in touch with the engine programmer? Normally programmers do this thing called 'runtime debugging' where the program can tell you exactly which line of code is causing the crash. It's a little hard to explain -- but Microsoft Visual Studio (the commercial version) is capable of remote runtime debugging. I'd be happy to run a debug build (after all, we're all running beta versions, no?)

I program some C++, I know what you mean.
He's kinda out of touch, but thats something Devs might be able to help you with.
You can try and contact him on his twitter.

Well, that does allow us to center it on the game itself.
Hmm.

I have a lot of random ideas, but most unlikely.
Someone with a better understanding of the game's workings needs to come in here and posit their theories.
