From now on, you are able to activate more than 3 sectors, but you are not allowed too!

When activating more than 3 sectors, you have a certain risk, your risk depends on the amount of illegal sectors (activated sectors-3).

When you get caugt, you will be fined. The fine equals the profit of 15 turns of all your activated profitable sectors. (Because else when you would be losing money, getting fined would be a gift.)
