Teleport to party member brings you to a wrong(unexpected) location

Hi!

I'm doing campaign for a new character.

When I'm in cruel (seems like an important detail), and people want to trade... They accept the invite, I go to cruel act main location (happened twice in act 2 cruel!), a person teleports to me (using party telepot to member icon) and the other person ends up in my hideout!

Thank you.
