I have been having a very big problem with J'zargo lately, i don't know when it started exactly but sometimes (usually when i'm in caves and dungeons, etc...) J'zargo stop equiping any weapons and doesn't fight anymore, he also doesn't wait when i tell him to and he follows me in a really weird way (without moving his legs).
This bug is really annoying me since i like J'zargo and we make a better team than with the other companions, is there any way to fix it? if not can you please fix this in an upcoming update.
Thank you.

J'Zargo only fights when he wants to But on the serious side you should reload a save. It usually fixes most things

Is it something like this???http://www.gamesas.com/topic/1392390-problems-with-mages/
