Better start a new game, he is using different flags and had reworked a lot of the scenes so basicaly while checking the requirements for the scene the game starts over at scene one because of missing stuff (wasen't there before) and so you get scene one.
You could just work with that and have your money and all but some events wont trigger that way.
And to be honest, it is not that hard to get all the girls.
"finished" the game yesterday and only river took me a little while because i hate her with every fiber and didn't talk to her befor it was unavoidable.
BTW little spoiler: if you finish moms "quest line" you are forced to replay a scene every night, he said its a bonus, i think its anoying
PS: sorry for the bad english, its not my first language
