Like the title say i dont get rewards in Dungeons. For me it was in the Arcanium Dungeon for the white potions. After fighting stage 6 of it i do Not get anything. 

After that i want to dmg the Clan Boss.  I have damaged him 800k after he killed me, the key is lost. Fine, i thought and take some closer look on that billboard who have done most of dmg. 

So: my first try today is there. But the second is not. The second 800k dmg from today are not added to the 860k of dmg from today morning. And my key is forever lost. 

My decice is an Samsung Galaxy S 7 Edge actually. 

Maybe it could be something to do with the todays server issues. Please fix that problem too. 

Hope to get my key back and make my secobd round again.  

Ps: no error message occured and Screenshots are not avaiable, too. 

Maybe you can see it in my Account.
