i made the screenshot right after i noticed the screen go black / blank. i made the combat log visible to help find the bug. i actually noticed the fleshblight zombie (who had on my turn walked 3 spaces away from an enemy grim well and lost all his ap) he then at end of turn went manic 2 squares towards the enemy grim well stopping next to it. the grim well did not stop either of his 2 squares manic movement. the screen went black right then. i remember there was still visible in the black/blank screen one of those yellow arrows that usually hover over the selected champion. but it was just the arrow not any champions or anything else visible. thats all i know.
