I reverted the changeset here: https://www.openstreetmap.org/changeset/168579807

All the relations elsewhere in the world were restored to their previous state.

@Flap Slimy Outward: your work to create road relations in your area was preserved too, in most cases through new relations.

The comment by @limes11 is correct.

To create new objects in OSM, you should give them *negative* numbers and the API will create them for you.  On the contrary, if you use *positive* numbers, you will ask the API to re-use an existing object having that number.  That created the mess here, because your upload requested to edit several relations that were already in use and move them to Colorado.
