Delve disconnecting user when entering through the portal

When in a party on PC entering the Delve portal from the hideout the user entering the mine will get disconnected back to the character select screen.

Also When in the mine there is no way to go top side from the action menu. Currently have to log out then re enter the mine via the swirly go to button from the parrty.

This issue was brought by 3.26 and the workaroud I found for it was to create an instance of Mine Encampment by accessing it from any town, which then allows party members to use "teleport to party leader" and enter the zone w/o a crash. Still, it will not help us much at this league, cause we cannot access nor interact with the crawler in a party.

Could You guys please take a look at that and possibly fix the problem for us?
