On any level, I can click "Test", and the editor will ask me if I want to save (Yes, No, or Cancel), but no matter what I click, nothing happens, and I always have to manually load up the world and get to that level by myself.
I already set the game path, I'm pretty sure. I went to C:\Program Files (x86)\Nifflas\FiNCK and selected FiNCK.exe
There must be someone out of the 35-ish active users on these forums who knows how to fix this.
