Same problem on iPad Air and iPhone 10x 

I reported the same issue as well. No fix. I even had a moderator come in and say the issue was resolved. Obviously it wasn’t. 

Same problem here. I have wasted energy, multi battle turns and much loot because my team was failing. Please correct. I habe screen shots if needed.

It also does not only happen in multi battle. Have been unable to level, get loot, etc.

Yup multibattle is broke for me to no matter what you. Heck it removes party members

The same. Auto battle removes any champion with full experience except the party leader. Have been defeated multiple times not realising a player had been removed. 

I have the same problem since the update. Multi battle is Donald Ducked. Unable to put two level 50 heroes in and two training as it bins the second maxed one and then I get a loss. You have ruined this facility ☹️
