Bug with items having charges when they shouldn't

I added mods to an existing world and I think that they generated items with charges when they shouldn’t have. For example,

Debug: item FMCNote was loaded with charges, but can not have any!
Function: void item::io(Archives&) [with Archive = io::JsonObjectInputArchive]
File: src/savegame_json.cpp
Line: 2150

I tried to delete the mods that I added, but no dice. I have no idea how to fix this and, being the brainlet I am, have no backups to run back to. Please advise.

You can safely ignore this, I find that it goes away after awhile. And then I’ll be wandering around another day and it’ll pop up again. Really doesn’t seem to affect anything that I’ve noticed.
