In the Economic interface, does the number of factory icons in a state show investment per-turn or so-far?
Let's say Penn has a War Supply output of x. I set Penn. to 3 factories for one turn, get a message that Philly built a steel mill. Penn. War Supply output goes up to y. On the next turn I decrease the number of factories in Penn. to 0. Does that mean:
(A) Penn. continues to produce an the elevated amount of War Supplies y as a result of the initial investment.
(B) Penn.'s war supply contribution drops next turn without investment, but not to x.
(C) Penn.'s war supply contribution drops back to x
