During the 2WK if the Halifax conference succeeds any occupied territories the Germans take automatically go to the NFA, but this means Germany won't be able to put any planes up in any French territories and also limit their supply as the NFA will likely not have a supply connection to capital. I suggest that Germany still take control over any metropole territories during the 2WK then have the option to give it to NFA.
The early peace conference over FRA while GER and the Entente are still at war with ENG causes these issues too if player GER agreed to the Halifax Conference.
