The game has added autosave for the first slot. Just for such cases. Just save to other places.
Checked the changelog and it is there so it's my fault for not reading the whole thing, just saying that'd be more helpful as a 1st line thing rather than the very last line in the changelog. So am I stuck since I saved over file1?
Played this a few time like at v4 and v6 but I'd always lose like 1-2 hours of progress cause I didn't save often and was used to renpy rollback/autosave, why I kept saving every 10 minutes on this version cause I know I forgot to last versions.
Edit: I managed to fix it by teleporting to bed and sleeping, IDK if this'll fuck up everything, guess I'll see.
