Thanks to @LouieK22 for discovering this issue.
When using any method or function from NavigationService, it throws the following error:
However, the wiki documentation for NavigationService is as follows:
This isn’t a particularly game-breaking issue, but if a feature is disabled, it should be marked as such on the wiki.
I used to do this, but I’m no longer part of the wiki team and they aren’t doing this anymore. It was done by mirroring the ClientAppSettings onto a page on the wiki, and I had templates setup that would hide themselves based on the value of certain FFlags.
With that said, the NavigationService is being removed next week, as they decided to just move the new members into the PathfindingService and deprecate the old API. It will disappear as soon as the API Dump is updated on there to reflect that change.
This really needs a better solution
