Squad Outfit Issues
Now I just stumbled upon this when I was playing with my friends, but I observed that whatever clothing they equip on their characters, I would actually be seeing the outfit that I have equipped on my characters, on theirs.
For eg: If I had route 66 leather pants on my kate, I would be seeing all other Kates in my lobby wearing the same route 66 leather pants. On their screen, if their kate is wearing the new blue outfit, then they would see all other kates in their lobby wearing the same blue outfit with not even the slightest difference among them.
This is not a game breaking issue, but hey, an issue is an issue. :)
