Update: I managed to get the cluster_token to work. I had something in the wrong folder from the start, so that was my bad. Now I'm just trying to figure out how to mod.
I have seen several members reply with the issue that the cluster_token is invalid and I have yet to see an admin or moderator address the issue. I followed the instructions of the main post to the letter, tried requesting a new cluster_token again and again, and nothing worked. I also don't see how we implement mods we want to use.
