syncthing: Incorrect sequence entries created spontaneously

Something is bad with our sequencing stuff. This is my log for the last couple of days:

(“my id” lines to indicate when syncthing was or wasn’t restarted)

There are no dates, but the latest bursts are yesterday (~20:37) and during the night (03:53 and 04:29). There are no changes to my files at those times. There were likely rescans. Currently, this computer is busy scanning a lot of “changes” in one of my larger folders; because the file entries were rewritten perhaps? Which is why I noticed this, because of the activity and notices.
