Interesting... I was wondering if missing mills is a thing. OK, it's just a mill... but I too am missing one, from my original farm (currently in position 1). The mill on the farm in position 0 is still there, and I have at least one neighbor who is also missing a mill. Just FYI. Maybe they are the pre-facilities days mills?
Idunno, and don't much care, actually. It would be groovy if we could store gifts or run facilities before I run out of bait... but whatever. I'm partyin' like it's 2009, lol.
Actually, I'm relieved my farms still exist; full stop. I've got mighty used to the place
