I've been trying to comb the Forums for this, and haven't happened across it yet. I've noticed that when I team with people for certain events, we don't always get placed within the same instance. Most of the time, I've been able to just switch instances and join them where they are. But there are other scenarios, like the War Zone mission, where you aren't able to change zones at all. Keep getting the "Not allowed" pop-up. Is anyone else seeing this? Appreciate any tips or information.
