I want my Raphina back, she is my partner

I was playing a campaign focused on Raphina Nierbloom's story and the demonic contracts, until it seems that Raphina disappeared after we hired more characters for the party. She no longer appears in the interactions, and when I mention her, I can no longer click on her name to go to her character sheet. Furthermore, the map is bugged; we were supposed to be in the sewers of Baldur's Gate, but the map threw us into the middle of the sea.
