@wirkey I believe that is just the default behavior around liberating capitals on just about all maps. I haven't play many games that I've seen it happen so don't have a strong opinion either way on it. I'd have to leave it to @Hepps if that is how he intends it to work or if he would rather the territories not revert.
No, in all maps I know it is the other way:
revised for example: If moscow is occupied by Axis, any territory orignally russian being captured by UK or US from Axis becomes UK/US with the possibility to build there.
It wouldn't be that big issue (other from not getting the income) if TWW wasn't so prone to logistics. Not being able to build AFs in China or Far Eastern Russia is a huge problem for Allies. Especially as China's capital is a long way from the Sea.
