Game-breaking Act 2 Coop Medallion bug

I was playing with my friend and we did the medallion quest but after he interacted with it it’s completely bricked for me. I can interact and see the pieces placed into it but I cannot choose my buff or interact with it in any way. This bug was present last league but since the buffs were so minor I just ignored it but this is game breaking now that the reward is a charm slot.

Yes me too. Please patch

Happened to me as well, exact same repro steps: playing in co-op, my friend could finish the quest and I couldn't because I'm on console.
Please fix!

I think my friend had this bug, he placed the two pieces I think after I did but wasn’t able to see the buffs, they’re on PC I’m on PS5, I had no issues.

They initially tried leaving the party but still didn’t work so I told him to restart game and try again in their own session (no party) and he said that fixed it.
