Im on telo and i was givin some weapons to give to some bounty hunters or sometin like that. When i get to the door at apartment B3 they tell me to come alone so i drop off my party members somewhere and go solo but when i get there they say again to come alone when my party member are on the other side of the map. So i was just wondering if there was a specific spot to leave your party member so they will let you enter?

you need to de-select your party members from your screen. De-select them from the choose party screen.
