I've discovered that you can now upgrade your ship using a fake license, but it seems there is another alternative method of upgrading your ship, I assume the legit way.
What are the advantages and disadvantages of upgrading via the fake license or the other method?
The fake license seems like a really good choice to me since I have no idea how to even go about upgrading it via the other method, I'm guessing I need to do more main story missions or something. However I am reluctant to do it this way as I fear that there may be a disadvantage. Maybe closing some possibly side quests or something, I don't know.
