I suppose this is a bug for every quest, but I only had done it once on the quest Craftsman Rescue. I accepted the quest, chose to try elite. Naturally, it was too hard so I chose to restart it on normal. While in normal I noticed the towers were 2 shooting my units and my army of 30 units, with 1500 health from my Epic card I received when buying premium civs, died before taking out one tower.
