The day has come... the meta data format of spritesheets changed somewhere, so renaming the sheet no longer works!
To fix, first make sure that Unity STILL doesn't support renaming sprites without breaking references. I suspect it might be fixed because it looks like they've mapping sprites to IDs instead of names.
Make sure to identify what version this breaks in, and keep the hack for previous versions.
