My board just died

Platform, device and operation system
Android via Nox emulator; nothing has been altered

What were you expecting to happen, and what actually happened
I don’t think anyone expects your BOARD TO VANISH.

How often does this happen? When did it begin happening?
You tell me, did this ever get discovered in testing?

Steps to make it happen again
Play the game, I guess. I did this in a challenge, maybe try playing a battle there.
