Auto synchronization NC-client v2.6.0git

Hello guys!
Many users reported me about broken auto-sync feature in the 2.6.0git of NC-client. It’s happens not every time, but very often and regular. Version of client’s OS does not matter. This problem appears after upgrading to 2.6.0git version of NC-client. Version of NC-server does not matter. I saw auto-sync problem with 16.x and 17.x NC-servers.

If I’m doing “Force sync now”

Everything became fine

Did somebody see this problem or I’m alone with this bug?
