New Update Not Downloading

So I heard about the new 0.2.2 or whatever update for Nimbatus, and decided to hop on and make a nuclear drone using the new TNT.

However, after going onto Nimbatus, nothing seems to have changed. The TNT weapon and Dynamic Thruster aren't there. I started a 2nd save file and it still isn't there.

In the file explorer, it does say that the file 'Nimbatus' (the game startup)  was modified on 14/11/17 (current date 18/11/17 if you didn't know), see pic.

Can I have some help?

EDIT: Ignore the attachment, that's the date i got the game.

EDIT 2: Nevermind! I 'downloaded' the game a second time, and it saved all my progress plus got the new items!
