I attend a university, so I can't exactly change my NAT type, but even with a strict one through the Blizzard app, destiny played just fine. Now, I can't load into the tower or properly see my friends list/join up with friends. I played a Rumble crucible match, and that worked perfectly, and I can load into the EDZ and other destinations just fine. It seems that only the tower and my friends list are not working properly. Any help beyond "just change your NAT type" would be greatly appreciated.
