Opponent uses ability and game loses connection but doesn't?

Twice now I've had games where the game timer will go all the down to 0:00 but will not actually end. It's always on my Opponents turn when this happens. It's like we've disconnected but the game doesn't actually register this. Not to mention if I concede or just close my app and re-open it I lose rank because the game counts it as a loss no matter how the game was going :/.

Below pictures are 2 different games in which this happened (I was to impatient to wait in the first picture as the Yellow count down timer went down to 0:00 like 3 times and I knew the bug was happening again)
