Hi mate,
It hasn't changed there are 2 versions.
The one you normally use via the download tools section.
And the Custom Tours.ini which uses a csv.
The csv version was requested by admins who are running a different set of maps to AAOTTS, by this I mean they have more or less than us and don't want the default ini generator.
So with the csv version you make a text file with your maps listed 1 per line. Then uploaded to the server, which will then give you a tours.ini for those maps listed in the file (csv).
In summary, you can continue to use the original tours.ini generator and manually add in your extra maps.
TT
