Currently a user can temporary add an adventure location by using the cli command location zoneid name, however I expect that a majority of users aren't aware this command exists as it does not appear when typing help. I propose that after a user manually adventures in the relay browser, mafia would scrape the adventure again link and automatically add the location if it doesn't exist.
I also propose that the text be changed from Holiday: location name to Override: location name to make it more apparent that it is a temporary override. Or as an alternative the Go Back to <zone> link could be scraped, so the correct zone could be given as the maximizer uses this information.
Also the cli command should probably appear when typing help.
This should help prevent users from creating local versions of adventures.txt and zonelist.txt, which could cause confusion when they inevitably forget to remove the local override files.
