Bug: Me and my girlfriend can't party up on the same network (PC)

So I've been playing a bit since the game started a few days ago. I've been able to play with my friends just fine. We've done invites through the friends list and joining parties through the multiple ways via the quest options. My girlfriend started yesterday and she can party with them all fine as well. The issue lies in the fact me and her can't be in a party together, doesn't matter how it's started or who is leader. If she's in the party I get an error that I can't join at this time and vice versa. I'm assuming that it's because we are on the same network. Is there a possible work around for this at the moment?

Yeah, I'll add it in there in a minute.
