Opening the door-no bugs at all, although you can skip ahead early by glitching through the door with your sparrow but nothing will trigger in the raid unless the spire is formed outside. Speed runs of VoG consist of teams sending 3-4 guys ahead and having 2-3 stay behind and open the door properly for maximum efficiency
Conflux phase and oracles also have no glitches, although you must be aware when you jump down into the middle to start the confluxes you can just die when you land, for no reason...really rare thing though
Templar (HERE WE GO), stuff we encountered while trying to do flawless over about 8 attempts before completing it. #1 Relic didn't spawn at all. So you know, you can't damage the boss. #2 Relic doesn't cleanse the mark by an oracle (which is only way to get rid of it during templar fight) #3 detain glitch, when you drop templar shields half of your fireteam will get detained, you break the shield, but it doesn't remove the debuff from you so you are stuck there, unable to move and just have to accept your slow death. #4 Relic fell through the damn floor, our relic bearer drops relic after shields go down to fire a few rockets, yeah relic just disappeared.
Gorgon/Jumping Puzzle, no issues here
Gatekeeper encounter, this also applies to atheon encounter, the portals on VoG are insanely glitched, you cannot sprint through them or walk through at the same time as another teammate, one or both of you won't go through and just pop out the other side, but your screen still fucks up as if you went through
Atheon encounter-#1 Atheon doesn't teleport anyone to get the relic, oracles still appeared inside the portals as well, and of course we couldn't destroy them. #2 pretty similar to the first, but there were six of us and he teleports one guy inside, which means we had to rush open the correct portal and get in there and help the poor guy struggling to juggle the relic, shoot oracles and deal the enemies. #3 the relic shield was bugged as hell vs splash damage so you could be hit inside the shield if you were standing near a rock/pillar.
