So does he just not work or is it just an animation issue?
Tahlkora and vekk use to do no animations for me but they used skills fine.
they would not walk, no no attack or casting animations, and when they died they would still be standing up.
I fixed this by moving me dat file to another location and forcing GW to build a new one by doing an image.
Sounds like that is what you are talking about when you say he is "sliding across the ground".
Hope that helps.
