The dev-drawn Mount Rushmore (originally released in US Update 1) no longer appears. I checked just before SU5 and just after SU5. Further, the World Map (post-SU5) shows it in the wrong place. The actual monument is near Keystone, SD, and the visitor’s center, parking lots, and such remain in place – but the mountain they lead up to is featureless, just how it was in 1.0.
Are there other US features that have disappeared?

The only mod I run is “We Love VFR,” and the developer ensures me he has no objects in this area so it should be no factor.
