This was a previously reported bug before the old forums were archived and frozen...
The old thread is at:
http://www.wowinterface.com/forums/s...ad.php?t=48738
When traveling with the main map up, if you are attacked, the game simply freezes...have to Cntrl-Alt-Del to get the task master up to kill the WoW process, reload the game, come back in and your dead...
This happens so often, I have tried to train myself not to use the main map...
There's no error log to post, nothing appears on the screen except a frozen main map...
This happens on latest github version just last night.
