I just used my second key on the EASY clan boss and I had 730K damage, somewhere right there, and it didn’t compute it again. It didn’t even show I used a second key just now. It only shows the 606K from this mornings attack. It’s the 4rth time it’s not taken damage I’ve dealt on record or the one time showed over  -1.34M in negative damage with 3 keys. I have lost loot from the clan bosses when I couldn’t deal enough damage and now I’m loosing the higher loot boxes and it’s always times 2 because we almost always beat him. 

I love this game, I’ve spent so many hours on here...I don’t know if I can see a tracker but I’m sure you can see one...and plan to spend a lot more and I know there’s bugs and I love that you listen and fix them which is why I spend money here and will continue to spend money on a game I love. Just hate missing rewards you can only get in that one place once a day. 

It was like I didn’t use the key at all after it was over. I’m pretty sure the clan boss still had less damage than when I started, so he took the damage just didn’t record for my account...for loot purposes.

Hope this helps.
