Multiplayer Vaal Temple Progress Bug

Hello,

Whenever my friend and I play coop together, they don't always get their vaal ruins temple progress. I will be at 1/6 crystals and they will be too, except after doing 5 vaal ruins in maps, I am 6/6 and they will be at 2/6 or 3/6. Their progress seems very inconsistent. When we were doing campaign, it was very consistent about us getting vaal temple ruins progress.

Thanks.

Getting consistently hosed by this bug here as well, makes the whole mechanic awful.

Of note, since this last patch, this seems to still be happening and feels a lot worse when you're supposed to be getting 2+ crystals as opposed to 1. I have had this happen in 2 and 3 player groups. It seems to happen most often when one player's temple is about to finish by activating the beacon on the map. This happens even when all players are in the instance and are close to the beacon before we activate it, and happens both in campaign and maps, although map issues are more egregious due to you getting more crystals now.
