Hello! So, I was having the itch to play After the End again, but knew that it wasn't compatible with 2.7.2., and I was directed to github, because I heard that it's relatively up-to-date there. So I download it, and I noticed through a few test games that everyone had the Iqta Vassal obligations law, as well as a few other bugs, such as Californians having access to the Sky Burial for some reason (and from what I'm reading on this subreddit, the game crashing whenever the pope dies at a certain date?). So, I searched through the pull requests on github, found the fix...and where do I go from there? Do I proceed to copy and paste the fixed stuff into their corresponding files through Notepad ? I don't see a download button anywhere. Can I download them and replaces the files with these edited ones?

Please forgive me if this is a stupid question to ask! I've only ever really used github this once. So I could download a relatively up-to-date version of a mod that I love for a game that I adore, so github is new to me in every other regard. So, if anyone can explain how everything works when it comes to github, I'd greatly appreciate it.
