Spoiler and bug warning I suppose....
I'm in Rosa's apartment, and the ghost has appeared and is fighting with Joey. I've gone out to the hall and hid, and now am back in the apartment. The ghosts have appeared again, and I clicked on the item that glows and have it in inventory. however, the ghosts disappeared when I clicked on the clipping near the door, and I can't select them anymore. I think this is stopping me from continuing. If anyone has encountered this and fixed it please let me know, I saved but they're still gone when I reload. Otherwise I guess I'll start over from an earlier save.
