Re: 1.1 terrain affordance with stuff
DoTerrainChangedEffects passes along thing.Stuff to CanBuildOnTerrain, but that's not good for blueprints - blueprints don't have .Stuff, they have .stuffToUse.
So wood wall blueprints don't get their wood stuff passed along, and are defaulted to Heavy instead of wood's Light, and are considered invalid for light terrain (e.g. bridges)
