I must be missing something, I unzipped the file into the folder with the exe and nothing is happening.
I just tested it myself, with the latest game version (1.1.0.1) and the latest mod release build (1.2.0 at the time) and it worked fine for me. I've made an update to include the mod version in the overlay that will release shortly (ten minutes at most) that you can try, and that I can confirm definitely works. If that still doesn't work, please open an issue on the repo tracker and we can try to figure out what's wrong.
