Dual Wield bug
 

This doesn't seem to affect PC's, only NPC Monks.

The bug is, if the NPC is a Monk and the NPC is using a two handed weapon, they still get offhand fist attacks.

I tested this on a MONKGM and a MONK class npc.

The MobAI.cpp call to CanThisClassDualWield() returns true for all npc's levlel 14+ and the next check allows all monkgm and monks to attack with thier offhand with no check for weapon type.
