I have the same problem, i’m gonna try the Infantile mode now. Spend over 200 bubbles only for that purple assassin.
For anybody else with the problem, the assassin in the picture seems to be the problem.
The achievement “Butterflies and Viscera” was bugged when I tried. In the story at Fort Salma.
I killed all the Mordrem Wolfs and Jungle Tendrils without letting one of the Bone Fiends die. Eventually I slayed the Mordrem Boss and the mission said complete but the achievement wasn’t finished apperently. (though the mission had the title ‘Complete’)
When I went back to the place of the boss I found the boss which I already had killed, and the mission sort of started again. I could do this over and over.. the boss keeps spawning and the achievement cant be done.
