Failed to load [filename] Referenced by [function]

I’m getting the error after deleting a folder that I’m no longer using. The stupid thing is I’m getting errors saying “Failed to load XYZ file” that wasn’t in the folder I deleted and the file it’s failing to load is right where it thinks it is. Why the Eff would this happen? Fix-up re-directors doesn’t do anything. It’s also saying that my Character BP is referencing a file that isn’t actually used in the player character but in an NPC.
