When a female attacks with a two handed weapon the left arm sinks into the model and is stuck there until relog.
It is a bug from base NWN.
I am reporting it because I found that when you have monkey grip + a shield the 1h animation is used and there is no bug. So a scimitar can be used without bugging the model.
I don't know if the base issue can be fixed, but if the animation for two handing weapons on female gnomes were changed to a 1handed animation, even without monkey grip, it'd eliminate the issue.
please help a serial gnome player use 2hand weapons again
