I assume its related to me being a big fat cheater and giving all of my characters lone wolf.
Yes, this is a known issue.
I will let you guys decide whether or not I should remove the talent, change the talent or leave it 'as is'.
Does this mean none of the four source hunters can have Lonewolf, or only two? EDIT: After trying it out myself, it gives me the message but doesn't actually do anything other than that. Will this cause problems later on?
Personally, I think it'd be pretty neat if there were more companions to choose from and your max party size was eight. Four source hunters, four companions. Possibly add a donkey companion whose sole purpose is to carry stuff. Can help in combat, but it's not a good idea to use them for that.
... or maybe I'm trying to make this game too much like Dungeon Siege. A party size of eight really would make the game very trivial. Perhaps a mod that not only increased the max party size, but the average number of creatures to compensate?
Or perhaps just a change to Lonewolf in general. I mostly pick it up for the bonus Ability Points. Of course the AP is nice too, but 2 AP per turn only allows me to cast one more ability every couple of turns.
If there's a way to change the negative effects of the Talent, that'd be awesome. Or make "All Skilled Up" grant 1 extra ability point per level and just remove Lone Wolf? I have no idea, just spitballing here.
