The game does not pull up the saves from the previous slot. I was still playing the spring build and somehow it's a pity 15 hours of playing the ftopku. But, as it turned out, there is a fairly simple solution - after creating a new save, it becomes noticeable that there is a slight difference in the names of the save files - v20 on the old, but already v21 in the saves of the final version. So you can just rename and may you be happy.
