So me and my 2 friends went though the second story mission a good few times today. On one of our runs we where all playing new characters to test them out. Sadly at the end of the map where you need all players present to spawn the boss we had a Montana go rogue. He kept running to the start of the level and just chilling ther then killed himself then repeated his actions.
I hooped out of our party chat to explain to him but he simply ignored me and my friends plies to let use continue. After a few mins we chose to quite as we where going no where. Sadly no of use got anything from our hard work in the level. We where all some what discouraged by this interaction and choose to start playing story missions in private.
I hope you have plans for a vote to kick system or as an alternative have the players still get ranked and reward based on the progress they did infact make.
PS ty for the amazing taste of the game im already addicted
