same issue here, i was able to load my saves from 3-3, and with the cheat mod still working so if you guys load a save before the 3-4 update, mainly around the dinner and when you meet rosiland by the car before going to the apartment or taking advatage of the deal, you should habe a close save to where 3-4 starts otherwise if you want here's my skip save to that point with some minor cheat mod edits, its also from the 4-1 compressed version
it'll be at the veronica choice at the end of last chapter, mainly focusing on the corruption style of the girls. Hana and Mina, are romanced, felicia is sugar momma, vernonica is more sub-ish/affectionate, and Rose in under Deal (no romance)
