Yea, it hasn’t been notifying me either, no worries 
I managed to nativize the sample project in 4.18, but only in Inclusive mode for some reason. Even exclusive with all files selected causes issues once the project loads. I have been able to launch my game project in 4.18 with the QualityGameSettings files nativizing (much more progress than 4.17 was allowing), but then I get the same problem with the “Unable to Get Game Settings Interface from Game Instance…” once the game is loaded, and the menu options and key-inputs won’t work because of it.
Sadly that’s the end of my progress with this so far lol
EDIT: SUCCESS (exclussive nativization in 4.18)!!
I managed to nativize the full quality menu project by adding every blueprint file from the Quality Game Settings system (except for example files, I deleted the example folder in my project) and excluding all enums and structs in DefaultEditor.ini EXCEPT for the Quality Game Settings ones.
The one last file I needed to nativize was my GameInstance file, which implements the GameSettingsWrapper.
Here’s a copy+paste of the “List of BlueprintAssets to nativize” (mind the last item, my game instance class). Other than the last item, this should paste cleanly onto your list of assets to nativize (note that it will replace everything that’s there):
