I left the game - put the tablet into standby - restarted the game after around 2.5 hours and
my Ajani PW has a life count of 21.
I do not know with which life count it had 2.5 hours ago. But as I had won all matches today I assume it would have had above the 80s.
I had the same things happen with Kiora. Opened that app in the morning and she was already close to dead like i’d quit out of a match.
