Starting actually on runway i/o above it.

[mongoose]

I have several bases; some of which are generic, so I understand ( I think!), why one can't actually start on them as they are not in the qclocations file, but I have made a generic into a specific, but I still can't start on the runway.
Here are the details as I understand what they should be. Any errors or something left out?

It seems all these issues were caused by really weird contents of some runway definitions files with width=1600 or something! I have no idea where those came from but changing that to 50 or similar fixed the issue!
