Hi Mahout,
What kind of system are you on, and what did the crashes look like?
Were they the ones where you can hear the game going on in the background, but the visuals have frozen? If it is, can I say that you've been extraordinarily unlucky? In the 6 months of developing NALE 2, I've played hundreds of hours of it, and I've only seen that bug about 5 times in total.
Unfortunately that's an ongoing problem that I'm unable to fix. It seems to be a plugin issue, but it's intermittent - when it happens, it doesn't correspond to anything in the script. I've had it happen between two dialog boxes before, with nothing between them. People have asked about it on the MV forums but there has never been a concrete answer.
If I ever manage to hunt it down, I'll fix it, but it might be some time. Thanks for reporting it though, because any data I have to suggest how frequently it happens is useful!
