I had an issue occur post nerf and buffs patch for hearthstone battlegrounds mode. I have seen minions swap places in normal hearthstone, but this occured today in one of my battleground matches and it had devastating results. To describe in detail I had 2 pack rats. My opponent’s minion attacked and destroyed my left most minion which was 1 of my 2 pack rats causing the deathrattle to trigger and summon more minions. Normally the minions to the right of the destroyed minion stay stagnant and don’t move locations, but this time my remaining pack rat which was directly to the right of the destroyed pack rat went to the furthest left position causing it to attack before my spawned minions from the previous pack rat deathrattle. This had a drastic impact on how the game finished causing a loss. I hope this gets fixed because it will ruin a game like battlegrounds if prevalent due to the nature of how the game works.
