I was playing traditional hobbit pre-release and lost a round because of a bug regarding warglings. I had two on board, beorn's hospitality as a creature, ravening warg, and little bear. I declared all attackers which should have registered as lethal with the +2/0 trample benefit from two warglings. Instead only one activated after attacks were declared . This left my opponent with 1 health left when it should have killed him. He was able to play removal on his turn and spiral from there. Genuinely insanely frustrating, I paid for this pre-release and I don't mind losing, I just want to lose when it feels fair
