Well... the point is, I did my math. And I came to the conclusion, that I would not be able to finish the 10 notes in time. So why waste 9 days of energy on collecting 8 Notes?

But if I knew that I had 20 days and not 10, of course I would have done the special quest. But once the extension was announced, I had, again, only 10 days to complete the quest...

Now I spent 6000 credits on energy drinks hoping to complete it. And it just might not work out for I would need 1 more days of extension
