Thank you! The saves are working. It worked immediately for 3 hours, and for 8 hours it only worked on SteamDeck via cloud synchronization. On the PC, it was in the second slot, “New Game,” but I turned on SteamDeck and the save was already working there. I didn't try 9999 glimmer because I already had it. Thank you!

I tried reuploading them but same thing, Not really sure why it's happened since it worked when I tested it, Apologies

The Glimmer one does not work either. Only the 3h does.

There's definitely a problem with the upload, the 8h speedrun is in the ConSaveSlot3 folder, but the files are named ConSaveSlot2_. Renaming them into 1 or 3 and putting into the respective slot folders does not work. There must have been a mixup when you copied these files from your system.

Not sure why GSerg, I tried myself before uplaoding it and it worked fine, I don't think putting my current 100% save would trigger the achievement, so not sure if there's anything I can do

The 3 hour speedrun works perfectly.
The 8 hour one does not, shows New Game in the slot.
