This application has encounteres a critical error:

ERROR #132 (0x85100084) Fatal exception!

Program: C:\Users\chris\Downloads\World of Warcraft - Mist of Pandaria\Wow-64_Patched.exe
ProcessID:8576
Exception 0xC0000005 (ACCESS_VIOLATION) at 0033:000000013F9B4057

The instruction at "0x000000013F9B4057" referenced memory at "0x0000000000000040".
The memory could not be "read".

This is a bug which seems to affect all MoP private servers. With most people, it's tied to certain locations, such as Stormwind, Orgrimmar and the Vale.

I keep my horde toons at Thunder Bluff and my ally toons at Darnassus and never have crashes there. I would have crashes pretty frequently when I'd keep my toons in Orgrimmar.
