Use the <WORLD> hack and ZwiftMap together!
This is nice to know about the ZwiftMap app:
Just curious – if you use ZwiftPref and select a route that is not on the calendar for the current day, the ZwiftMap app seems to only put the map up for the correct course for the day?There is a trick! Start ZwiftMap first and then start Zwift. Then it will detect which world is loaded in Zwift and switch maps. With ZwiftMap Classic for Windows there is not a problem at all — it reads through your log file at startup to detect which map to load at first.
