Well, I was modelling - doing usual stuff as always - theeeen, there came a problem. Since I deformed an object in edit mode, it became out of it’s origin point. I know, it happens all the time, quite normal. So, I just reset it with “Origin to Geometry” option. Untill then it was ok, but after that, I can’t do scales, nor rotations. ONLY locations. When rotating or scaling looks like only origin point is doing the tasks but no changes in the object. Is it a kind of bug or did I just forget to set something else? Oh, rotation and scale properties are also unlocked.
