Why immediately call it a bug? Perhaps quick battles operate under different principles. There are only two opinions here: either ban quick battles altogether or allow them without restrictions! Otherwise, there will be excuses like: "I forgot to turn off auto-battle, give me auto-battle" :D

P.S.: By the way, here's a funny thing: one Hydra takes a Hive without losses, but if there are two Hydras (in one stack), one of them is lost :eek: I don't even know how to explain this.
