So basically, I've downloaded the .zip file of a world into the minehut server dashboard. I see the name of the world in the heading of "file manager" but I can't actually join the world when i do the command "/world ul_[name of world]" I've also tried the commands /world 0, /world 1, and /world 2 but that only takes me to the nether, overworld and the end How do i join my world i uploaded to minehut?
