That happens every time you cross the portal at the same time, it is one by one, cleanse them once on the stairs and a second time in the middle an get out of there and go to the middle, you don't have to stay in there until they kill all the Oracles, I personally think the glitches make the fight more interesting, except for the one where the relic disappears when you are in the middle and everybody is inside banging Atheon, Other than that the glitches make the fight a real challenge, when everything works fine it is all repetition, makes me feel stupid.

Yes, this is always a problem. Sending the other two teammates through the portal first seems to help.

It is getting ridiculous! Now that I thought I saw everything the VOG still impresses me. Getting stuck in between portals getting teleported but on the other planet then my teammates. Jumping in the middle with the shield teammates asking me WTF I am doing next to the portal :D thanks god it was the normal raid and not the hard one. Hope this get fixed as soon as possible :)

When you run through, are you running through with another teammate? I find that this problem is solved by having one person go through at a time instead of everybody just bum rushing it out the front door.
