There seems to be a bug with the fishnet stocking, you might have to wait for 0.47finalok so im trying a lot of times.. in the beach if janice gets pregnant ... with jason and billy and still nothing... i tried like 6 times and .. still janice doesnt get pregnant... the walkthrough says that is 50% chanse but still nothing... and i already done the bedroom scene and it doesnt unlock janice "Fishnet stockings" either...
as for billy and Janice at the pier make sure to repeat the mom swap first
because I did it and it worked first time.
