Bug on uber ancients

Good morning,

Xbox console, character converted from d2r.

I wanted to report a bug in the new Uber Ancients activity. I discovered that it is possible to perform the activity multiple times with one set of keys. With 4 sets of keys, I was able to repeat the activity 6 times. Mechanism of the bug

Paladin, opening the portal in A5. After entering the portal, start Uber Ancients. After the fight, a jewel drops. I take the SC out of my backpack, pick up the jewel, and take it to the chest. I enter the portal again to take the SC. At this time, a warlock character joins the game. At the moment of entry, the paladin is in the uber section by the portal. When the second player joins, there is a momentary slowdown (tick) and a message appears about the player joining the game. At the moment of this tick, the uber characters reappear in their places and the mechanism allows for re-activation the sequence again.

On one set of keys, I managed to repeat the sequence three times. The first and second times, a legendary jewel dropped. The third time, a yellow random gem dropped.

If you have any questions, please contact me.

Best regards
