So. I'm dumb. I cannot for the life of me figure out how to play the mods, and absolutely no walkthroughs or videos online have been any help at all. I downloaded the full set from github, created my Mods folder, extracted each individual modlet folder (not ZIP) into the Mods folder, and... nothing. I'm clearly missing a step here, but I don't know what.
Also, I noticed when I viewed one of the ModInfo.xml files it says <Version value="A18" /> Does that mean it's only good for A18, despite being on the A19 thread?
Edit: So, I combined the info in all 19 ModInfo.xml files into one ModInfo.xml file, and put that in the Mods folder, and launched the game... and nothing.
