[Bug] Enemy towers reset at end of 2v2, a win became a draw

So my co-mate and I three-crowned the other team, with only half damage to one of our arena towers. In the transition to the "Winner!" screen with the confetti, the app froze, and I could see my co-mate playing cards, but not the results of their plays, plus the rest of the screen stayed the way it was at the end of the battle (I couldn't see the new troops my co-mate or the enemy were dropping, or any spells or anything; tower rubble remained in place; friendly troops already on the field remained at their positions near the rubble of the enemy king tower).

My co-mate was playing cards, but I couldn't, my deck and elixir had vanished for the transition screen. So I went back to my phone's home screen and then opened the app again, nothing had changed. The "OK" button (or whatever it is you press to go back to the main menu after the end of a battle) also didn't pop up, so I couldn't exit that way either. I brought up the Android "recent apps" menu and force-quit Clash, then re-opened it.

When I re-opened it I was instantly dropped back into the same battle, the enemy towers had somehow been rebuilt, and my co-mate was fighting for their life against the forces of both enemies. Our arena tower that had only been half-damaged was gone, and with me back in the battle at the last minute we were barely able to force a draw.

I went back and watched the replay and was able to find the moment of divergence, but nothing remained of our original victory, nor were the battles counted separately in my battle history - I could only find the draw, not the win.

I have no idea what the enemy saw from their side - if their loss turned into a draw, if one of them force-quit the app and relaunched it only to be dropped back in part-way through the battle with me now staring at my home screen wondering what the heck was going on, and my co-mate probably thinking I'd abandoned them.

I wasn't recording at the time, and I don't habitually record because it slows the game down too much, nor am I really able to record replays - same reason, not that it would help much in this case anyway. So I don't have any way to prove this REALLY weird bug, but I don't have anything to gain by lying, either. I'm not looking for my trophy count to be adjusted or anything, or to get a chest (my chest slots were full anyway), but everyone needs to be warned that this could happen.

TL; DR: if you reach the end of a battle and the screen freezes with no chest/winner display and no button to get back to the main menu, immediately force-quit Clash and relaunch.

Oh, one last thing before I post - I was glancing at the sub rules just now and it occurred to me that although my first thought was that this is a bug, it could also be cheating.
