if your using the old save file, that could be the reason, if not then i'm not sure, the things you missed are: the forest archer. and Femboy hooters scenes, that take place in the bar. when you play the bar mini game, if you did and they arnt showing up then I gotta look into this. the second Boss showing up there and in the wrong slot is usual too.
