I did the bunker buster, went to collect the resource chest and a second one popped out and stacked on top of the first one. I got the capture, will upload it soon and edit my post with the video
Can confirm this happens when Bungie servers are on the fritz. A few weeks ago I was in the Warden of Nothing nightfall, in the boss room. We wipe because the game didn't despawn the enemies, despite the boss being dead for 30 seconds and the chest & dialogue going off, and when I respawn, I'm at the beginning of the insight terminus strike??? Got totally hosed out of my nightfall loot.
