So, hi! I got a contract about going to the mun. Seemed pretty easy, from what I did in tutorial, I tried pretty hard, until thought about finishing the tutorial! But every time I can't complete it, because of this phrase: "I suggest you start ASAP!" I don't understand what he means by that, but what do i do, when he says that? Do I wait for the manuever or do something else?
