So I went to download the newest update for the beta, but I wasn't sure if I already had the previous one. I considered downloading the entire game, but took the chance and downloaded the 901 MB update.
When I tried to install it, I was told that I needed the previous one. I immediately thought, "damn, what now. How do I even get that one!", but then I read the prompt, and it said that it would take me to the site where I could download the missing update. And so it did. It opened my browser to a page with the link in the middle of the screen.
Everything worked and there was much rejoicing.
This is how easy updating a game should always be. I salute the person in charge of this.
