Hello
Can someone explain to me why some options are in black (inactive) and some in green (active), previous turn both -2 production were in black, now they are green. Now I can't use last option for wrenches or machines (3 engineers + 3 coins) - I have enough coins and engineers of course and I think they were green last turn so it kind of spoiled my plan. What is the rule for that?
Regards
