Got problems with two BTSync programs (2.0.128 (36)) in the same LAN. I turned on my wife's slow netbook and it started syncing with my fast notebook. After an hour I noticed that syncing was complete. But there were several *.bts files on the netbook side and corresponding files were DELETED on my notebook (source side)! I checked and found that all *.bts files had correct contents inside. Ok, I will try newer version now.
