Hmm...
Maybe it could put out a warning that you are referencing the file you just deleted.
What I am actually up about with this discussion is if that addon would be a good idea to make.
Manually changing hardcoded filepaths is really bugging me. I guess I could make an autoload but then I still have to change the paths manually. Another solution would be exported packed scenes, but larger scenes could eat up your ram pretty quickly.
