had problems with this in the beta so really hope this gets fixed soon, when im in a party with 2 of my mates,whoever hosts & starts the game gets seperated from the other players in the lobby & gets put into a different game,the only workaround we found is to invite the host into the game that we`ve been put in,but this doesnt always work out because of no spare slots in the game ,also another issue i`ve noticed is that sometimes a players perk & perk level doesnt show up for some players for some reason
