Other than Russia transporting factories east to the Urals before the Germans reached them, I find it hard to accept any factory being used (by anyone) after it’s tt has been captured in combat. Therefore, simply remove them and give the captor a cash bonus for acquired assets. Or allow them to build (in their own home factories) any new tech units the enemy had developed.
I think you got it….
In fact not remove it but give the captor a cash…
For minor factory give the value of the territory in cash.
For major factory give x 2 the value of the territory in cash.
Even a liberated France “building” anything other than infantry in Paris is unhistorical
I totally agree….
