Editor Save Broken

For some time now i have this weird bug, if you can call it that.

I expand folders and gameobjects(in hierarchy), which i work upon, and everything is fine, but when i go to a break or stop for the day, and open unity again - all folders and objects are collapsed. The weirdest part is that sometimes if i close and open it again, everything is as i left it, but most of the time, its collapsed…

I noticed this is happening with unity 5.x, or at least i started noticing it then.

Anyone have ANY idea what the problem might be with this? Since i have started working on big project, this really ruins workflow and slows me down :confused:

Noone?
