Doing that didn’t work exactly but i managed to solve it. Remember how i said my transmutes backups weren’t applying different presets of illusions? So, thats because a file called transmutes.cst (CST not GST as usual). This file seems to appear only when using the cloud saving, and once i removed it, it reseted my illusions, but i still couldn’t get my illusions to be added, even though i was getting the successful message in gdstash. The problem was, everytime i tried to delete that file, the steam would create it again.
So i moved the saves to local saving and then i could delete the transmute.cst file and all the illusions were actually being added to the game, but if as i tried to return to cloud saving, the steam create the file again and all my illusions got reseted. To pass that, i had to delete all my cloud saving through the network tab in game options and after doing that you can import your local saving to cloud saving and that way i get the game running with all the illusions.
Strangely this time, steam didn’t create the transmute.cst file.
