I have discovered what I think is a bug with the new hit 3 mechanics when attacking enemies where there were more than one adjacent enemy (which is now dead).
My example happened in the xmas event when I hit the central enemy (in this case Buddy) with Tibertus’s special. There were previously 4 minion heroes but 2 were already dead when I fired the special.
However only Buddy was hit and inflicted with defence down, the other 2 minions were not affected. Could the mechanics be trying to target 2 missing minions ? IDK whats going on TBH.
