Unfortunately I don't have a video to post for this bug but a simple google search from what I describe is enough to find it. Basically my fireteam and I just beat the spire of stars for the first time, or so we thought. We took the boss down to zero health got to the part where you throw the orbs at his shield one last time and then he did the death animation. Of course though that wasn't the end. Instead the music kept going and then enemies constantly spawned and despawned instantly with finally us being engulfed and playing hot potato again until the boss wiped us. We looked it up thinking we missed something but nope. It was a bug, and when looking up the bug we find forums from June AND July about it. It has been how many months and this bug still isn't fixed. I understand bug fixing is finicky and sometimes fixing one spawns more but this is ridiculous. It is extremely frustrating spending hours doing this since it was the second time we tried it and the first time we ever beat it having this happen and we are all insanely pissed to say the least.
