I'm half way through Tier 2 already. Please raise awareness for this, it will affect you when you progress past Tier 1.
Without fail, someone in my lobby will waltz up to the Tier 1 story mission infil (an exfil marker that still spawns on the map for anyone to use) and it will teleport ME from wherever I am on the map into the story mission.
The final nail in the coffin is realising the game is over for you. You will lose all your pack-a-punch weapons & perks because-- the only way out of the story mission is to finish it and exfil.
I've finished this final mission 10+ times now because without fail there will always be someone in the map trolling.
