So I tried to look this up but unfortunately I don't understand computers very well and I have some extra details. I got the "failed to load corrupted : (" message on my save were I have completed the a, b, and c sides, all the regular strawberries and one golden strawberry and working on chapter 9 on assist mode. I got Celeste through itch but play it with a steam shortcut to use a ps4 controller, there is data in all three saves, the middle one being the one corrupted. If anyone could offer any assistance I would be be very grateful
