Yes, basically right now the navmap is loaded from the instance available here on the forums, which obviously uses data files generated from Discovery. I plan to rewrite some of its code to load data files locally but this is quite complicated.
As well as making Wingman work with other mods/vanilla, this improvement would also mean that Wingman's maps are always guaranteed to be up to date (right now the navmap needs to be manually updated by @Error / @Alex. which typically introduces some delay after a new Discovery version is released). There is an issue to track this.
