Ehehe, so the script hack was no good in the end... I hope it doesn't occur too often, it's frustrating that it exists but I'm kinda at a loss sadly. I'll give it a run on my laptop sometime and see if it happens there, so I can at least see how bad it is!
It's okay -- as I said, it's annoying, not gamebreaking.
Oddly, my GF plays on the same machine and has had far fewer battle crashes. We use separate user accounts with separate installations, so maybe we somehow wound up with different versions? Was there another release within a few days of the one that fixed the lockups? I can't find a changelog to check.
