You shouldn’t have to - I recompiled it with the latest version from the release branch (which should match the latest release)… Are you using the build from the launcher, or are you perhaps building from another branch? Because if you’re not using the release branch, then you are going to have to recompile I’m afraid.
Also, I created the most basic Blueprint you can possibly create that covers pretty much all the basics - sending your score to the server, receiving a reply and printing a field from the reply. Might be useful for some!
