After lounging around dancing in 'Skyline' for quite some time collecting loot, I jumped back to the Tower to refresh and clean up my inventory. As soon as I spawned, I noticed my HUD had disappeared. The next thing I noticed was that my Ghost had too, which meant a whole new array of problems to do with travelling arose. I skipped into a friends Fireteam, hoping it was just a bug in this instance of the Tower, but to no avail. This persisted for a few hours, even after I logged off and relogged as the same character. Restarting the console seemed to fix it, but I'd thought I'd bring it up just in case there was some underlying theme that caused it. ...I'd also love the addition of an option to remove the HUD.
