Twice now I've had, for reasons I can't explain, a folder on my Mac somehow gets renamed from "backgrounds" to "Backgrounds", and then syncthing complains it can't sync the folder for a day or two because the folder is still "backgrounds" on the other clients(which I usually don't notice until I go back digging through the logs), and then somehow syncthing deletes all of the files in this folder on all of the machines, and then spits out a steady stream of errors complaining it can't sync files because no machines currently online have these missing files that it just murdered.
