So, how do we restore those tags?

Wait a minute! I didn't delete it, I *drew* it. I visited that site, walked all those trails while GPS tracking, and entered all the data from the flyer. And it's there. The problem is, the outline of an "archaelogical site" apparently doesn't show up on the map. The name of the site shows up, though.

Looks like a mistake. Is there a way to restore it?

Yeah, that happens. In general *ALL* of those polygons need to be deleted, but I can't get to all of them at once. I have to sleep sometime. And sometimes I don't make it back to where I was working before.

The practical difference between a motorway and a motorway link is that, when you zoom out far enough, the motorway links disappear. They do that right here on OpenStreetMap's own renderings. When the links are used to depict a regular cloverleaf intersection with a surface road, that's OK (although it's still not ideal IMHO because you can't tell where the exits are without zooming in). The problems occur when the intersection is not a regular cloverleaf but rather the point where one motorway comes to an end by merging into another motorway. The ending motorway invariably splits into an arrangement of ramps, as 31 does here. If those ramps are depicted using motorway links, they disappear when you zoom out, leaving the map looking as though the motorway just ends out in the middle of nowhere. It's confusing when you're actually trying to use the map to plan a route, since it looks as though the motorways don't connect.

I agree that all of those ramps should be one-way. Changing them from motorway links to motorways should not impact their oneway=yes status; if it's not oneway=yes after, it's because it wasn't oneway=yes before, which it should have been.

I don't remember editing that particular area, but I do more deleting than adding on OSM. Georgia, in particular, is covered border-to-border with a "camo paint job" of farms and forests, none of which bear any resemblance to reality. Whenever I have some spare time, I delete them wholesale. I also delete scads of small roads and service roads that have evidently been drawn in at random, have no connection to reality whatsoever.

95% of my editing is deletion, mainly that ridiculous camo paint job all over Georgia. If I see a road that's really there but just out of place, I'll move it. There are LOTS of roads -- especially service roads -- on the Georgia map that simply don't exist, though, shown going through corn fields and lakes.

There's a lot of nonexistent roads on the Georgia map, so I delete a lot of roads. These didn't seem to exist in the satellite photos -- at least, not in the locations shown. If they are there but that well camouflaged, well, I apologize.

Why in the wide, wide world of sports would you be inputting crops, meadows, orchards and woods? Those things don't belong on OSM maps *unless* they actually have a proper name. Just general vegetation is pointless clutter. I've been on a mission to *remove* a whole lot of such pointless clutter all over Georgia because somebody thought it was a good idea to import some gov't data on woods, farms, and wetlands, and most of it had absolutely no correlation with reality, it just covered the entire state map with a camo paint job. I just continued when I ran into your more realistic data, sorry. But, really, don't put that garbage on there, please. Not unless it's a place with a name.

No! I was just cleaning up a mess on the map, disjointed roads shown that clearly did not correspond to the roads shown on the satellite photo. But it's a weird road, to be sure, looking as though it doesn't actually connect to GA 37. I guess I should have added a note for someone on the ground to confirm the roads and road names.

I had no problem driving around in it. I presume you're supposed to pay a fee to actually camp there, but I'm not sure how you'd represent that on the map. Permissive maybe?
