Ah. That's what I figured, but there was no reanimation done. I guess the problem probably was that when I eventually long rested, I had finished the revenge quest?
Short rest doesn't do anything and also doesn't heal any minions
I remember an animation once happening but only the very first time the skill was used and it was in combat I think.
Sometimes Glut will leave and the quest finishes, this should not happen. This always happens for me when I move Glut into the Tower or near its entrance in case that is relevant. Also Glut gains new abilities like a haste-cloud after resting and sometimes after reloading.
