The document now has a section for things that turned out to be nothing

In the interest of intellectual honesty, four entries have been moved to a new section called Resolved As Nothing.

One was a reflection. One was a compression artefact. One was a bird. One was me looking at the same shape twice from different angles and getting excited, which is the same error every fan map on this forum makes.

Entry five remains. Entry six remains. The port remains under investigation.
