Hallo. 

Im here to report a bug of something. It's a black screen comming out of nowhere and locking the game. The only way out of it is through closing the game. Today i had it again on clannboss and it restarted the game out of nowhere.  This is very annoying.

My phone galaxy s7 android 8.0. With newest raid update installed. 

I hope u can fix this because it wastes cb keys which u only get 1 every 6 hours. 

Bye and thanks
