I really hope it gets fixed because I'm pretty deep in, starting over would cost me countless hours of progression so i absolutely want to avoid that.
You can also try a backup save, use the cheat for items/wine, and see if that gets through. I noticed in my runs using item/clothing cheats that they didn't negatively impact the game, but I wouldn't advance time too far with cheats if what others said is true. Plus, with some quests like Mira and apparently now Dani, having some time component element, that makes sense that it could cause problems.
To your other comment about Rachel and softlocks, similar things happened to me with her but eventually she just started appearing in the gym again on certain nights (it was random from what I could tell), but much later like around 3am. She also goes to the soccer boys, but they don't acknowledge that she's there which maybe is just a matter of there being no content for her there yet. As for the bitching, she appears there randomly for me too only in certain bush terrain that triggers the image of her being there. It doesn't actually show her icon as there which can be frustrating. She also apparently goes to night beach volleyball sometimes too, but that's also random I think and there's also no scenes that I could find there either.
