Crash During Loading Screens?

Shatt loaded fine, tried joining an EOTS and the loading bar froze and after maybe 30 seconds the game crashed and displayed the WoWError box with the "report what you were doing" thing. Tried logging in again, same thing. Tried a different character in Stormwind, same thing. Tried a 3rd who was also in Shatt, was able to log in. Queued some BGs to test from this one, WSG worked fine, AB worked fine, EOTS crashed at the loading screen.

Disabled all addons and it's still happening.

Ideas as to why certain zones are causing game crashes?
