The Vell-os map outfit doesn't function like a normal outfit. It's actually a crön resource continually granting the player a map outfit, so whatever system they're in gets mapped along with however many systems out the map outfit being granted specifies. Any outfit that lists 'map' or 'paint' as part of its function won't be added to the player's inventory when bought, as they are a one-time use function that maps systems or changes your ship's color.
So, unless I want to play with crons to make the map work the Map outfit is useless. I was thinking I was going to be hit with some simpler answer, but I can deal with not using the map outfit. It seems like they made one outfit a little over complicated though.
