Anyhow, here's the fixed patch. Would've made the .rpa, but i have no clue how. Fixes a bunch of crashes on mary/mom dialogues, including the office talk, kitchen helping etc. Also, unlocks normal bathroom progression, mom will gradually get more comfortable with you up until you hit 13 bathroom visits, at which point the menu unlocks for any bathroom scene. Also fixed one image not appearing during Lola office dialogue.

Install: unpack into "game" directory, replacing the scripts.rpa
P.S. after a pretty good intro, there's a ludicrous amount of artificial lengthening of the game with not much to fill it with. Hence, I recommend cheating in the $7650 required for story progression and forget about the matching mini-game alltogether.
UPDATE: Double checked, this does not cause to miss any current content, I just missed the latter 3 chat girls in my playthrough and also got confused by unimplemented scene pictures in game files (there are a few extra ones for morning sleep and morning clothes change).
