That sounds serious. It's the first I've heard of this issue, but I should see why it's happening since I'm already doing a fair amount of bug-fixing.
I'll do a little testing later, but when did this freeze occur? Did you talk to Genn first?
Oh, shoot. I just looked at that and I see the problem. That is major, and it locks out a lot of content, so it needs to be fixed now.
Don't know how that came about (because I've gone through this exact segment with no trouble before), but I need to get a fix for that out right now. I'll have that out tomorrow, ideally with some other bugfixes.
