"SetSelectedWireframeHidden" Does not work.

So i suddenly started to get this error with one of the Asset Store packages after importing.

 `UnityEditor.EditorUtility' does not contain a definition for `SetSelectedWireframeHidden'

How it does NOT contain it? It should contain it right? I’m using newest Beta, but this also happens with latest stable build. I tried to search Unity Docs to see if its name is renamed to something else, but no luck.

Anyone have any idea why im getting this error?
