Thank you for for your prompt reply. For anyone else interested, what ended up unlocking "Backrub" and "BJ" in "Time to sleep" was changeing the value of eventDoughterGoToBed to eight.IIRC I used save editor to make my save go back to one quest stage before. Then after doing last thing again it was fixed. If that doesnt work u can advance one quest stage, you wont miss much. Better than being stuck.
I musst also admit, that I just today throug this process found out about the "cheat sheet", which was very helpfull. Paticularly since it contains additional information, that is missing in the Walkthrough! Such as the last steps of the main event for instance.
