Vaal Temple automatically closed for party leader when exiting the temple while in coop

This is a horrible bug, if you open a temple while in party, all party members go inside then the host leaves the temple, for example a locking medalion drops and you port out to lock a room from the console, a thing that works while playing solo, when you access the console you will notice the temple was closed for you, even while the party members are still inside...

Horrible bug

Still happening and it's the most annoying thing ever. I can't be in a party if I want to do my temple.

This has happened to me several times. Very frustrating.

Build your temple solo. Invite friends when finish. I've learned it the hard way as well.

Leave the group before completing the temple, and this problem will not occur. We also struggled with this bug.
