Playing TFS campaign in a 3-person party on the Requiem mission. I was behind the other players and got a "joining other players" countdown and then a black screen for the entire mission as my other party members completed the level without me. I heard music and sound the entire time and was able to access my weapons. My screen came back after they completed the level. Not very polished for a $100 installment to game that has been running for 7 years and delayed release.
