Arena battle expired
It's been happening for a while now.
I'm at home, with wifi, I start the battle and click on auto, at some point I attend my toddler and leave the phone there, combat running.
UI unlock the phone after ~5 minutes, battle expired... But it did count and the characters cannot be used,is considered a loss.
Why!? My phone didn't lose connection, just got locked because of inactivity, and only happens with the arena.
