Getting errors when trying to fight stage 13 of Minotaur dungeon. Near the end of the fight, champs go blank with nothing showing by the health bar from the boss which flips to full health. Message comes up saying there was an error and it gives you the option to report it to the developers. This has happen more than a few times and at first I thought it was because of multi-battle. But after switching to just single auto, the error happened before.
