Well, I got the achievement but nothing in my game changed. Haha! No idea what to do with this. When you say "manually install," exactly what does that mean? I dropped the zip into my mods folder, but that didn't do anything.
I meant manually install as in what you did, the automatic install option doesn't give the achievement AFAIK. I had to uninstall the version automatically installed, download the file and put it in the mods folder, then restart the game.
If nothing shows for you after installing the zip clear you cache. If that's not working start uninstalling mods.
I figured it out. i did not realize it added assets to the maps. I thought it was its own map/scenario. I'm kind of a doof sometimes. Haha!
