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.
