Couch Co-Op: Vaal Temple is buggy as hell

0. In couch co-op after colleting first 6 crystal in campaign (probably same thing will happen in end game but it is not tested yet)
1. P2 opened the temple, which was working fine - we were able to choose who is using which bench
2. After completing the temple we noticed that number of crystals is not increasing anymore - it was staying at 0 (for P2)
3. After realizing that now P1 needs to open the temple we did that - but temple basically had all the bench disabled, and also we had a medallion drop but it was only visible on minimap and not visible nor interactable in the room itself.

In general it seems like Couch Co-Op became extremely low priority, which is indicative by the fact that we are now 2nd month in and it is still not functioning properly. I have noticed similar patterns in previous leagues, when this mode was very buggy/borderline unplayable, especially early in the league.

It is sad and I would wish that this mode receives more love from GGG. It is really fun experience when there are more than 1 gamer in the family.

The same. We tried everything, but 3 of 10 temples in local coop still doesn’t work properly after 0.4d, both of us can’t use benches and pick up medallions. It looks like no one of us is owner of the temple when it happened. We have tried a lot of tips, played maps separately and then open the temple etc, but haven’t found any logic. We were so happy after 0.4d patch note, but actually nothing fixed.
