Poe2 vaal beacon/crystal multiplayer issue

In multiplayer the vaal beacons only grant beacon progress for 1 player at random? regardless of who activated, or killed the last enemy, or opened the map, usually not the host of the party or the zone. have done a few tests and could not figure out a reasonable pattern to it, but its preventing the non host from doing the quests or league mechanic.

It clearly favors giving the league mechanic progress to the party leader, but it can give it to the members, and when it gives it to a member its only that one person that gets progress.

also tested if it was about zone ownership and no conclusive results.

Same. I don't know the pattern

Friend and I also ran into this, I was the party leader and was getting them reliably but he only got one every now and again. He was stuck with needing just one more and we did 3 and none of them counted. After transferring him party leader the next one counted.

I'm also experiencing this and I think it's whoever renders in the beacon first is getting credit. I've been following my teammate and he's reliably getting them now. Weird trigger
