Version 1.2 of the Quest Map and Navigation System, the version mentioned above with the bugfix that removes use of the HUD and instead converts the system to pure UMG, is now live via the Epic launcher. This will change the integration process very slightly, and I will be publishing a new tutorial covering this in the next 24-48 hours. Those who are adept with blueprints will likely be able to take the current integration tutorial and work their way through that without needing to wait for the new one. Thanks for your patience in this matter.
