Texture mapping on mesh problem

Welcome. I have a problem with Rhino 6. I have an object with mapped texture and I make mesh from this object. When I squish this mesh the texture is mapped incorrect. In Rhino 5 everything works fine. Any advice would be appreciated.

Picture? How is it incorrect?

There are on left surface with mapped texture, mesh form this surface with the same mapped texture and squished mesh but the texture is incorrect.
