Update problem in Production screen

[ncc1701e]

Select an Armor Corps for building. The default Advancement chosen is Breakthrough with attributes on the right.

Selecting Heavy Armor as Advancement instead and the attributes are indeed changing.

But, selecting once again Breakthrough as Advancement and you can see that the values are no more updated.

Try with the 40 Advancement selected.

Units at '39 technology are all the same (I think it should be tweaked but that's another story).

Pratically an Infantry '39 is the same be it Assault or Antitank.
A Fighter '39 is the same if Interceptor, Escort, or Fighter-Bomber.

The differences are felt as you tech up. (Given potentially minimal differences, less than a handful of points)
In fact in your own screenshot the one with 'better' stats is the '40 Breakthrough one.
