I went to fight the clan boss and it had a error pop op three times. Then logged out and back in. It used my boss key even though I did not get to fight the boss.

Hi! 

As you write this issue looks something connection problem. If this issue still persist connect to our support and attach screenshot from error screen to your report. 

Hello, so I went to fight clan boss and it went well until half way through fight then game crashed. When reloading game I lost my key and it shows no damage to the boss. Is there anything I can do to either get key back or advice so it doesn't happen again.
