I fought the Oooze now several times with 3 or 5 gambits. I win the fight and get the reward but the achievements “Triple Threat” and “High Stakes Gambler” are never shown as completed.
I finish this in Revenge with a Warrior and are always ported out dead even though I have skilled 100% rally on kill, therefore I should not be dead when killing the boss.
Even though as I get a reward it means I won, therefore the achievement should be completed, but it is not. 100% reproducible.
It works fine this way unless I add a gambit, then I always come out dead and get no achievement.
