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
