I was doing the Swamp King today, and my wizard was in line with both the Tan Mold and Duke Oggenwhat. The Duke was on the centre of his magic circle, but I don't think it is supposed to do anything to protect him. The Wizard was 4 squares away diagonally from the Duke. I got to move the Tan Mold three squares immediately as if it was the only enemy in LOS. Annoyingly, the Duke had 1 HP left and I intended to use WoW to kill him. I mention it in case it was relevant. Or it might be something when you target two non-minions in PvE I guess.
I did indeed. I can't remember if it was on, but that seems the likely explanation. I guess this bug report can be ignored.
