Another bug where pop-up elements either stay on completely, or only partially fade out. This time it was a riven mod objective at the start of a deimos exploration run. Seems to only happen with free roam environments, possibly due to the way they transition from a hub area into an active mission setting.
Just completed a run through fortuna bounties, and got an achievement progress pop-up for play time. (I played SIGNIFICANTLY more than 100 hours on this acc, but whatever) Not really more to it, it won't go away, even if I open menus and remains layered over them, obscuring the UI.
