Ok so when I started a new skirmish game and placed my first Barrack, I clicked on Infantry and it took like a second to train. After my second I placed another Barrack by my ally's base and then i clicked on Infantry. When i did the fog clock over the picture of the soldier did not move and it never did finish, it's like it pauses before it even starts. And this problem also affects the rocket, medic, and engineer. Does anyone know what the problem is?
