Yes, it was the Diana footjob booty call. I had it, but had not played it.We do have the same problem did you manage to get or find the missing one or it is because of un-played booty call from the phone?
Edit: If anyone have the same problem with the 7/8 booty call it is because of the Diana new booty call (Call Diana and you will have a short lines of communication and after that play the scroll and it should complete your missing booty call).
Nice choice of games in your signature btw. I wouldhave put Freeloading Family too, but only 2 possible choices unless I cheat with custom multi-game banners.
