The problem I was facing was following the guide for the nightly build (link), and the url for it does not exist. I tried this both on tortoiseGit and the linux terminal.
Example:
~$ svn checkout https://svn.itms.ovh/nightly-build/trunk
svn: E170000: URL 'https://svn.itms.ovh/nightly-build/trunk' doesn't exist
In other news I downloaded the code from the svn repo https://svn.wildfiregames.com/public/ps/trunk/ , and ran the bash script you provided, which it made it extremely easy to get the game running. Thank You!
