While I like the game so far and I like that it let's you choose for nearly every lewd option or relationship option, the bar night followed by the beach scene the next day is off. If you took Mia home and fucked her, the MC then lies about it when asked by the fmc, she then says she hates liars. So I went back and chose not to take Mia home but just be a good wingman. The next day on the beach, you get two choices, if you chose to tell her about last night, it acts like you actually did take Mia home and she is mad because of that(even though she let Amber rub her twat, at least in my playthrough, that morning). The coding is definitely borked. I tried the fix posted above to line 24 of script2.rpy, which took care of the menu but she still did not believe the mc, when he said he went home alone and you get the scene with the ex texting. So it seems you are damned if you do, damned if you don't.
Edit: I spoke too soon, later on our boy has our back and she realizes she got mad over nothing. Stop making games that are this true to life, dammit.
