I've used syncthing without problems for years, but then recently had an issue where it seemed to duplicate an entire folder of files and all their contents and whenever I would delete the duplicate it would bring it back. I was really annoyed with it until I realized, it's actually OSX's fault, because I renamed a folder from uppercase to lowercase, and there's no good way for syncthing to handle that when you have case sensitive servers syncing with insensitive ones. (Linux and OSX in my case.) Moral of the story is, don't rename a file only changing it's case-- add a dumb character or something so it can sync to more civilized servers properly.
