Mercenary Samuro bug

Somehow Samuro is bugged, when I have him in a party, I dont get any quest from mystery. In any other team combinations I often get quests. To test is out I first reinstalled the game. Then did level 30 bountys in 3 hours with Samuro. I didnt get 1 single quest. Then I went to use Nature combination and got a quest every second or third time using mystery.

So somehow Samuro needs to be debugged so I can use him. His a good merc and is used for many bountys, so its really annoying.
