Crop tool in photoshop CC not working (solved “problem”)

Well if you drag some photos to your photoshop CC canvas, scale, rotate, position them as you need and select crop tool it could fail. Or better say perform no visible action, the outer parts of images remain where they were i.e. no cropping occurs. This could be because these layers are smart-objects (whatever it is) )) and have special icon on the layer list. The solution is to rasterize those layers before cropping. THat’s it, thanks, bye!)
