Hi !
I've just played a game as Soviets with an Hard US against a Hard WE and a normal WE. The game was on McGaechen. That's was a nice and quiet game that i won.
Near the end (we had the 3 cp and axis had env. 100 points), my barracks and my tank depot couldn't build anymore ! I had more than 50 pop left but it didn't worked. On the other hand, the support barrack could build anything.
I could add what i wanted to the list but the production was stuck at 100%. I can send you a replay, but that is all i have.
