Did you check outside the garage? Literally outside the garage door.

Sorry for missing your comment, I expected itch.io to send an email if I got a reply. I checked on the roof and the immediate area around the base (in front of the atv bay, by the big yellow bins, the area out front, etc). I did not, however, scour the map. If it was just delivering to the wrong coordinates but with the sounds in the right place, I don't have any idea where it might have been delivering. If it is out at Yankee, or in the backrooms or something, I doubt I would ever find it.
