We continue to see enemies magically reviving after being dead for 1 or more rounds in the tower. These enemies aren't being resurrected by a living enemy. Often, these enemies have even been consumed by a hero like Hopper or Zomm.
This bug feels particularly acute now that we are going through 2-4 teams of heroes just to take down a single barbarian floor. This is a serious bug. I don't understand how it has not been addressed.
