I did start a new game tho but my version is 3.5.u need to start a fresh game then after u trigger the father asking u to leave the bathroom, just set fool to 100 and follow the steps it should trigger the scene, just do not set any stats at all. I tried it twice and it works. You should not try to shower again and again once it doesnt trigger the save is useless and a waste of time.
fyi, it would seem that the cheat is embedded into the save file so if u still have the cheat version use that to get that scene to trigger then edit all stats after u got the drop soap scene and install the Deluded v0.3.5.1 over that cheat version overwrite and the cheat will activate too on that save game press F1 for cheat menu.
if u delete old save with cheats u will lose the cheat function somehow cheat is embeded into the save game.
