Fixed. The Helios Tower elevator was already in the map data as a scripted route, but the script was on the dead list so the portal resolved to nothing. It now runs in both directions — 2F up to the top, and back down from 99F. One note for the record: a test in our suite was asserting that this elevator stays dead, which was correct before your report and wrong after it, so that test now checks the real destination instead. Re-test both directions.
