I was part of a king's fall clear and one guy came in and just insta killed every boss and was glitching through walls and flying. As a result i got all the regular gear of a kf clear like normal but i also got all the encounter triumphs for free. I already reported him, but is there anyway for me to undo my triumph progress or something? What do i do? Edit: forgot to mention that i already have touch of malice if that affects the situation
