BB, I'll take the heat for 10199 being a bit late. When the beta testers got this patch we had like a day to test it. I thought I'd found a crasher bug in the patch. I pressed the panic button. I think the HotFix ended up getting held back because of this.

In the end it turned out it was a bad download, not the patch causing the crash.  Seems we should have beta tested the servers too.
