I recently deleted the many-months-old stash of a Git project I hadn't worked on for a few months. Without reviewing it, I know m-) Upon compiling the project about 30min later, several folders and file were missing. Pretty surely I didn't accidentally delete those through the Finder (they weren't in the Trash). After a restore from Time Machine, all worked out fine.
However, I'm left wondering whether there is any conceivable scenario in which files and folders in the working directory, were somehow attached to the old stash?
