Larian Studios Forums Baldur's Gate III Baldur's Gate III - Multiplayer Discussion Can't join as NPC only

Hi everyone!

Hope there wasn't another thread like this, I’ve searched the other discussions and didn’t find anything that solves my problem.
I’d like to play Gale’s origin with my girlfriend joining me as an NPC so that we could progress every companion’s questline and cutscene. We’ve read some guides and we understood that was possible by switching who she is controlling from time to time to interact with everyone.
We are both playing on PS5 and I’ve started yesterday a new single player campaign and everytime she asks to join/I invite her by accessing multiplayer menu, the game makes her create a new Tav. No way to avoid it or to assign her an NPC before she joins. We tried even with an old single player save in Act 3 and lvl 12 characters: she joined and the game automatically kick out an NPC from the party to make her create a new tav.
Did we miss something? We can't understand if that's a bug or if maybe multiplayer mode has change.

Thanks in advance for your time!
