Hello—it looks like a few things were broken or made more complicated in the changeset:

- The sand polygon surrounding northwestern Vegas (https://www.openstreetmap.org/relation/19087109) appears to have been broken, as it no longer renders. This could be an issue as simple as an 'inner' member added to the relation as 'outer' or vice versa, or perhaps two disconnected ways.

- I've noticed that you have snapped a bunch of boundaries and multipolygons to Moccasin Road (https://www.openstreetmap.org/way/14311102), and this is problematic for a couple reasons. Generally, you should avoid snapping things to roads that don't physically intersect with the roads (same goes for footpaths and waterways), especially large relations multipolygons and administrative boundaries, because you want to make an edit to such a way, you also have to edit all the relations attached to it and risk breaking them in the process. I've seen cases where a straight road serving as a boundary between two entities is added two each respective relation, but once a city boundary, a Native American reservation, and two or three natural area multipolygons are linked two a single unrelated routable way like Moccasin Road, it makes editing things more difficult and makes the objects more fragile, such as if an editor adjusted, split, or retraced the road in such a way that neglects the relations attached to it. Furthermore, it creates a massive bounding box (those red/blue squares that appear in the changeset history that show where edits were made), thus making it more difficult to see what simple edit was made because so many other things were also accidentally editied.

- Additionally, Moccasin Road here is not a straight line, whereas the Paiute reservation and the Las Vegas boundaries are relatively straight. In reality, the boundaries don't arbitrarily wiggle across the desert along an informal track road, but follow markers and fences on the ground that follow the same section line that Moccasin is located along.
