I have not but I have seen some glitches during gameplay. Example: - During Patrol on Mars (Barens), there is a point on the location that I'd get shot by an invisible static (would not move from the position) vex. If I got close, I could see the glowing eye and the shots coming to damage me but nothing else. It was like a ghost from a previous spawned vex killed in the location. It only disappered once an event started on the same location. - During POE and Strikes I see many times enemies suddenly spawning in front of me and then quickly disappering many times. The bad is when I get killed by the glitch. I only noticed something like you mentioned during the Archon Priest Strike Nightfall. At the stage where you have the clifs close to the docked spaceship on the far right side below, I many times like to snipe the enemies down first from the high clif. It seems Bungie created a patch to force players to go down as I was using many different weapons and the enemies (even lower rank) seemed immune to all shots. Once I got closer, the weapons worked as usual. Good luck with all you do.
