Crashing in Borean Tundra...

[LechonKawali]

I have just recently taken to leveling an alt and started questing in Borean Tundra and found that if I right click a target to attack WoW freezes and subsequently crashes. I have tested this on multiple toons and with different combinations of mods (e.g. all on, all off, nUI only, etc.). I have found that with nUI on I can generate the bug, however, if I turn it (nUI) off no freeze.

Any help would be great.
