Game crashes mid-fight

Platform, device version and operating system
Android, LG GPad F 8", Marshmallow

What you were expecting to happen, and what actually happened
I am unable to complete ANY battles. Mid-fight, the game blackscreened and to restart. I wasted all my invasion sigels today on this.

How often does this happen? When did it begin happening?
After the update.

Steps to make it happen again*
Unknown. This could be an issue with the tablet itself. Memory leak maybe? Or bad resource management maybe… I’m going to swap this game to my backup tablet until the issue is hopefully resolved.
