We played the game with the 4 of us. For a couple of reloads the game worked fine, howere after that, we would see dofferent things play out. For example my friend used a shot changer item (the item that changes live to blank and the other way) and shot someone else dealing 2 damage, according to his point of view. Howere we the rest of us seen him using a saw and firing a blank. These different actions happened multiple time through the game. Even tho we changed sessions it still occured. It seems it only happens if there is 4 players, when we played with 3, everything was fine.
