I don’t know exactly how it happened. but I noticed that my files started to spread to all my folders. I have a server on a raspberry pi, but the problem just happened on my pc. I found this log and it looks like there was a problem with the folder ids. It was a headache trying to find where the files went and put them back. I don’t know how it works, but syncthing doesn’t have something to prevent it from happening?
