At the first stage of the strike you are to fight off 3 waves of Fallen and Hive(stage 3 only) until your ghost has completed removing the laser obstacle in your way. Behind the ghost there is a second level catwalk where most tend to fight off the waves using distance and a stack of cargo crates as a defense. On that catwalk, if you stand at the broken railing or further away from the crates, enemies will randomly despawn and then respawn(fully healed) in the corner within a few steps of melee range. Normally in this situation the enemy must jump up to the catwalk at the broken railing to get within melee range. I noticed this event occuring several times as i was going through this weeks Nightfall strike solo for an exotic bounty i needed to complete. I hope my explanation of how to replicate the bug is clear enough for Bungie Staff to comprehend. I'll do my best to aquire some sort of photo/video proof to avoid confusion of what area i am speaking of. If this turns out to be sleep deprived babble and no one can make sense of what was said then i apologize in advance. Other players and readers, if you happen to have something to add that i may have missed/misinterpreted, please leave your input to help Bungie find a solution as soon as possible. Thanks, i hope it helps.
