Me and my partner share our Steam Libraries, which allowed her to play the game and earn unlocks, as she was technically playing on her own save.
We've tried playing alongside eachother, with her using the Friend's Pass.
This, however, has reset all of her previous unlocks, and doesn't allow her to use those that she earned previously, nor get any new ones (other than just earning them, and "unlocking them after buying the full game).
She isn't allowed to start any matches on her own, either.
Which worked fine, while she played from my Library.
Clearly, there's some sync issues regarding Steam Shared Libraries and the Friend's Pass.
Any solutions to this?
