I had lone wolf on one of my mc's and recruited jahan for my much needed magical ability control.
Well I got lone wolf again and Jahan left I went to the hall of heroes where he told me there was no room in my party... when I had just me and my female MC without lonewolf. Apparently lone wolf doesn't reset when you respec so the game thinks you have a 2 full slots when its only one.
I guess i'll play dwarf fortress till this is fixed really annoying. I really need Jahan for his utility abilities and my female MC won't be able to keep up with the damage with Jahan missing.
Try getting into a fight, it may correct that. I took Glass Cannon but then backed out of it. My character was stuck with half-HP and it would not go up at all. Then I got into a fight and it fixed itself.
