Seems you refer to this object, http://www.openstreetmap.org/way/341791043/history

When I first looked at the map, it was rendered correctly as building and name; however refreshing 
the page made it disappear.

So it looks like a glitch in Carto or in the rendering database. Do not immediately recommend 
tagging changes for such reason.

I have opened in ticket in Carto:

The object history has 4 versions, none if the edits is by by woodpeck_repair.

no that should be fine. If an amenity fills a building, the amenity tag can be on the building outline.

That would be a mapping regression, since the school fills the building.
In the specific case it looks like the campus should be mapped.

This is not what the wiki says. It says "Mark the boundary of the school using an Area Area or place 
a Node Node in the middle of the site" thus it does not exclude having the amenity on the building.
