It truly is, I have never looked at renpy/python code in my live before this, but the style of the dev is really not that great.
And adressing all those who didn't bother reading previous posts:
I fixed the "bug" in Hitomi's route. It is literally 2 missing lines of code within 300k+. The scene in question is in the game, it just never gets used. This scene and the ones to follow are not done yet, but have the dialogue written, if you want to read them.
I have attached the extracted files at the end and fixed the "Bug". Just delete the "archive.rpa" in the "game" directory and merge my "game" folder with the existing one and you are good to go. Took way more effort than i care to admit, but at least I now know that the dev is peepeepoopoo after studying his code and my god, everyone can do it. I found his problems and fixed his shit within one evening, even tho it ain't my code. I'd say happy fapping, but there is nothing to fap to.
Btw if you can't trigger the new "Under the Table Threesome" scene, it's because your route variable for the combined route of (not) mum & sis gets reset to 0 and will never change from that point on. Just use a new run or use a save editor to change "mumsis_route" to something between 13 to 15.
If anyone is wondering I am a software developer, currently doing my bachelor and this shit code is on an embarrassing level.
