I think you’re right. At one point it was possible to select event only routes via ZwiftPref and then ride then in-game but that hack doesn’t seem to be working anymore. I may remove the event only routes from ZwiftPref to avoid any confusion it may cause.

Until there is support for the ‘normal’ world hack in-game I won’t add France and Paris to ZwiftPref and zwift-preferences; but I’ll add it as soon as it works.

There are several ways to get access to both France and Paris already now. I know of four different ways you can do it in Windows, and two of them work for macOS, too. However, since they are probably beyond what Zwift would deem fair use — otherwise they had probably enabled the world hack — I won’t publish the methods here at zwifthacks.com. You will have to search for them elsewhere.

Hi Jeff, I’m sending you an e-mail because I need extra information to understand what it is you experience (or not).

When I select a new world in ZwiftPrefs and save it the world I have chosen isn’t available in Zwift.

In which way do you mean that it is broken? I don’t see a difference here.
The world hack works – as before – and lets you choose a world other than Watopia as base world.

However, I will publish an update at some point so ZwiftPref can display which courses/worlds are on the calendar currently
