5.6.3 p2 Unity and most recent AC.
I've deleted the menu and it's removed the error but I've still lost the guidelines that help you understand the boundaries of the drag and such. I just adjusted the drag coordinates and then got the error and lost…
I'm getting the following error:NullReferenceException: Object reference not set to an instance of an objectAC.MenuPreview.Update () (at Assets/AdventureCreator/Scripts/Menu/MenuPreview.cs:63)
