Yeah, just had a PVP battle…I had 3 monsters in team, 2 monsters left not in battle.

Opponent had two monsters in battle, very low health.

My Dreadwolf uses Slaughter, kills them all.

…I get 200 diamonds, and my streak goes from 9 to 0…

Umm…yeah, so I “lost” when I won…this happened a few times in the past as well.

Its happened to me once in a while, it is frustating to get when having a hard win, but i think they will resolve this next update
