I had copies of the same folder on my desktop and laptop, although the laptop had an old version from a couple months ago. I setup this folder to sync, but it overwrote the newer files on the desktop with the old ones. The timestamps on these files on both computers are now February 2015. This is with Syncthing v0.10.30 on Arch Linux. I checked and made sure both of the system clocks are correct. Also, since i chose default versioning, there are no archives. yay -_-.
That’s sad. 
The good news is that the conflict detection in v0.11 should handle this much better.
Thanks. Luckily the changes since then were not major, but its still frustrating. Glad its being worked on.
