Bug in Undercity

While I was trying to get to Sylvanas in Undercity, game crashed in Royal Quarter and this message showed:


ERROR #132 (0x85100084) Fatal exception!

Program: C:\.........\Mists of Pandaria 5.4.2\WoW_WOD_Models.exe
ProcessID:3928
Exception: 0xC0000005 (ACCESS_VIOLATION) at 0023:0144852F

The instruction at "0x0144852F" referenced memory at \0x00000058"
The memory could not be "read".

Any ideas how to fix it?
