I lost my progress!
How can I manually restore my save or delete it completely to restore the mod?

"MC_POST_SAVESLOT_LOAD" from "PST" failed: resources/scripts/json.lua:125: Unterminated JSON encoded object found at position in [] Stack Traceback: in method assert resources/scripts/json.lua:125: in function 'decode' ...ive skill trees_3305869734/scripts/libs/save_manager.lua:599: in function 'Load' ...ive skill trees_3305869734/scripts/libs/save_manager.lua:1083: in function at line 1076

As I understand it, saving comes from cloud storage and after losing power, it was unable to completely complete saving, can I somehow transfer it to local storage to fix it?
And if I understand correctly, it constantly saves data during a run only in the cloud and does not create additional backup saves before or after the run so that in case of a recording error it would be possible to boot from them

I'm under the impression that mod save data (as opposed to normal game savefiles) isn't stored in the cloud at all - if this is not the case then I don't really know how the sync with cloud is handled for it.
My understanding is that once a savefile becomes corrupted and the game tries to load it, it's effectively gone as the game will soon save the fresh level 1 savefile data on top of it.

This is why I made the backups addon .dll you can find in the mod description tab - once installed, it creates backups for you when starting a run, and once data loss is detected (checks that you're back to global lvl 1), a prompt shows up when opening the tree that lets you try to load an existing backup.

Mod data savefiles themselves are found in the Isaac installation directory, under "data/passive skill trees/".

the problem is that I installed the addon after losing data, then I tried to complete a couple of runs to rewrite but the addon saw them but couldn't install them, giving an error

and while I'm run, I get this error every frame:

Hmm yeah this situation would need looking into, I'll see if I can reproduce it by manually 'breaking' a savefile and see what can be done from there.
Unfortunately if the addon was installed after the data loss then the data is very likely irreversibly gone at this point, but this error chain could use fixing.

As a temporary measure, you can try moving your "save1.dat" file away from the saved mod data folder (Isaac dir -> "data/passive skill tree/"), so the game can gracefully regenerate one.

oh, i found a possible reason for the problem with loading the save
it is shown in these screenshots:

Yeah it certainly doesn't look recoverable - best bet to avoid the error for now is to move/delete the faulty files and let the mod regenerate a fresh one.
