Just to confirm, this bug and problem still exist on 1.4.93 beta to! All of peers PC are updated with the new 1.4.93 beta version. Android to, the newest version. I have synced a camera folder from my Samsung Note Pro 3 android, betwen linux and windows, and then, i have deleted the sync of this folder one time on windows machine, and now, on windows machine, i can't add this folder on sync, it say that exist on the sync, but, is not there. This is a big bug, and developers seems not be worryed of this bug. On android and on linux is showing that there are 2 peers, the windows machine to, but, on the windows machine, there is not this folder on the sync list, and i can't add this folder. And the problem is, that the images from my android phone are not done to sync, and will not be done on all other machine, like, linux, for example, because, this problem. Maybe should we use the new, Open Source Sync software: Syncthing (or newly, Pulse, on www.ind.ie), there are the bugs constantly repaired, if someone detect bug. Thanks.
