I forgot to mention, this error is constant and the Prefab Editor is unresponsive. I suspect I'm going to have to clear out a user file to be able to work.
 
Reproduction Steps
I entered the Prefab Editor after having tested in a 3.1.0 RWG world.

Did you also run the World Editor in the same session? In any case clear your saves folder and double check your mods folders if you have more than one.

I did not run the World Editor. Clearing profiles didn't help. I hate to clear my Saves folder. I need some of that. I guess I can just move it.

Ah, there. Renaming the Saves/Empty/PrefabEditor directory got it to generate another and I'm in. Phew.

I'll make that folder full of files available in the same place the log file is located.
 
I get random errors in certain instances when I switch between the 2, esp with other stuff like mods installed, save clear usually fixes, yeah just back the folder up. Toolbelt can def hiccup with overhauls installed using editors.

Hello zztong,

delete/rename the Empty folder in AppData\Roaming\7DaysToDie\Saves as you already did is currently the easiest solution.
I've been told this issue is caused by item numbers that are getting shifted in the prefab editor since they work a little different in there.
I'll see if we can get a solution for this that does not require the manual deletion of the folder.

I'll be moving the thread to fixed.

Best,
Revi

Thanks. It does seem like a low priority given how few users go into the Prefab Editor.

One possible cure would be if it were the Prefab Editor (and not in-game), catch the exception and empty the tool belt.

In-game, that might work too. I mean some player is loosing something. Maybe losing it all is okay? I'm not sure it happens in game, but it's a wild world out there.
