Unless any of you used a mod or for some reason saved
after the dev says to save, you shouldn't have any problem loading a save. However, if you have a save (even an auto-save, under the
A page of saves) from the final scene with Alice at the end of v2.4, that should load successfully.
However, in case you still can't load saves from before, I'm providing 3 here as attachments. The only difference between them is which LI the MC chose to spend the night with (after movie night) and commit to more than the others. I would also point out that you'll be one domination point deficient with any of them for a scene with Melissa in v2.5. So you might want to use a Ren'Py save editor, URM, or whatever to add 1 to the current dp if you want that path. Save 9-2 is for Alice; 39-2 is for Melissa; and 69-2 is for Aiko. All of them load at (that is, jump back to) the very beginning of the scene where Alice will give the MC a handjob at the end of v2.4.
