Well, looks like somehow my Carol quest got reset, the next Monday I got the chance to do the report again. Weird.
It did show me a new bug though. During the first time you are at Carol's house, and she runs to the bathroom. She magically reappears in her room ready to mess around. I talked to the new Carol and it's the usual home menu. If you go to the bathroom no one is there, but the dialogue happens as it should and the scenes all play fine. It's probably a bug due to now having Carol available in her place for sex.
