"Does the mage animation switch properly if you toggle it with the cheat console hotkey (ctrl 1 or something like that?
Yep, it switch as it should BUT ONLY after I uninstalled 1ppv3: Improved Improved Galactygon's Avatar Switching. While being installed it prevents BG1 char animation to work for current party members (they use BG2 animation even while their animations sets to L_XXXXXXX type). NPCs out of party uses BG1 animations without any problems. For example I have Minsc in Copper Coronet out of party and he use BG1 Fighter animation. But if I add him to party, his animation changes to BG2 one
