Maven's Crucible mission instance bugged

So I launched the map with the quest item after witnessing enough T12+ maps and every time I try to enter it kick me out of the game and show the instance crashed error, tried to switch servers but it's still bugged.

So now I have 6 bugged portals on my map device and I'm afraid that the mission will bug out if I try to put another map in to reset portals.

Any help/advice is appreciated...

After relogging today, the portals are now gone and the mission look like it reseted, so I have to witness another 6 Tier 12+ bosses.
