Save/Discard teams won't work

When i design a team and make some changes and then realize i have no energy, i tap back. The game pops up with save changes option, and i save, but it doesn’t go through.

I also want to make a statement about the war chest mechanism. It is unfair to lose the right to war chest from previous clan after you get a new one. You already bring a penalty wait in titan fight and you don not reward the wars not particopated. Why the hell should i lose chest share worth of 4 or 5 wars

war is a team effort as is Titan. If you leave an ally you forfeit your right to the team reward. It’s only fair to lose that chest count as there’s a different chest in the new ally and another way to reduce mercing as most reports so far claim 3* and 4* AM
