once i recruited soluafein i was dissapointed that his avatar wasnt the same as when he was a drow in ust natha, any way to change it back without crashing the game?

Mmm... Does the drow male avatar have a spellcasting animation? I think it does... If it does, I doubt there'll be a problem... Go into Shadowkeeper and switch him to a Drow Male avatar. Try and cast a spell before you do anything else. If it crashes, well... you'll know to change it back. If not, I don't forsee any major problems.

would changing armour be a problem? ive SK'ed him to a fighter, so he wount cast spells anyway.

Eh, just go for it, then. Shouldn't be a problem.
