Sometimes my game freezes for 10-20 seconds when the core is destroyed, when the freeze ends it says “the game has ended” and the only option is to quit to menu. After quitting to menu daily quests don’t get progress from the game, but hero progress and gold gets updated.
Thanks for the report! It sounds like you are experiencing some sort of disconnect when the core is destroyed that is preventing you from getting to the end of match screen. If it’s a graphics hitch, lowering/changing graphics settings may prevent the freeze from occurring. If it’s network related, please make a post in the Technical Support Forums with the following information.
