While I do not have a video of the bug occurring, I am capable of explaining what is happening. Every time I log into one of my characters, such as when I boot up the game for the first time or switch characters, randomly while playing I will get a "New Subclass Unlocked" pop up. It will give me the pop up for void, arc and solar, and it will happen without fail on every character. I am not sure what in game action I am doing which causes the pop ups, just that it seems to only happen when I have recently logged into one of my 3 characters (warlock, hunter, titan). And that the bug occurs once and will not happen again until I log off or switch. It is extremely distracting and has gotten me killed in some of my missions, and some of my buddies have been dealing with the same issue as well. Note: I've been playing this game since launch, and have unlocked everything for all three subclasses a long time ago. If you need computer specs, a video of the glitch occurring, or more details I can happily provide them. (Plus this bug only started after the launch of final shape.) To whoever is reading this, hope your having a good day.
