my dbd save editor stopped working

If you unlocked exclusive dlcs like golden Feng this will corupt your save file

i tried to remove them but still doesn't work, what can i do to restore my save file?

You have to inject an empty one and start building it again if you don't have a backup

fantastic, thank you

as it was said above, feng min's golden exclusives cause the corruption of the savefile, it becomes kinda not finished. I wasn't able to fix it simply by editing savefile code, there always was some mistake in it but maybe its simply because I'm potato brained.

solution that worked for me: swap her golden clothes in the game, lvl up couple of characters and savefile will fix itself.

That's the right thing you have to do, unless you have a backup that isn't corrupted (if you Have, inject it).
