I have a problem with Faendal. Suddenly he won't attack nor defend himself. He will follow me around and wait if I tell him to. But when I draw my weapon he does nothing. If we are attacked he does nothing but use potions. I am om PC and have tried to reset the AI. I have told him to leave and afterwards told him to stay. I've tried to whack him. All to no avail. I have a earlier savegame where he works fine, so all is not lost. Is this a normal bug and if so is there any way to fix it?

Well I have just reverted to the earlier save, but would be nice to know if anyone else have experienced this, to figure out how often it happens. Anyway, I'll make sure my followers works from now on before I end a session and would encourage others to do the same. Just in case.
