It looks like some creature models/textures are not correctly displayed in the toolset. So far, one of the orcs and bodak display 2 "superposed" creatues. I'm not saying it comes from the patch, just wondering?

well to clarify/proof that something is caused by my patch all you need to do is temporarily disable it via this method:
in NWN folder, rename xp2patch.key to 171_xp2patch.key, and rename xp2patch.key.bak to xo2patch.key, assuming you installed patch via installer with create backup option, if you dont have a backup of this file, you can download original here (uninstall).
And no I dont think its caused by patch, but screenshot would help.
