this is my error code when trying to make someone a speedrunner

Thanks for submitting this issue! Looking at your logs, I can see a few things that may be causing this bug...

• Please make sure all of your Discord Role IDs in config.yml are correct— for hunter, speedrunner, and spectator. If you don't need automatic role assignment, you can delete the three fields.
• Make sure your Discord bot has administrator permissions in your server, and its highest role is above your hunter, speedrunner, and spectator roles.
• Make sure your server's system clock is set to the correct time; if it is too off, network requests will be rejected.

If none of these fixes work, please upload your plugin config.yml file and I can further assist you!

what if i have more then one hunter

That shouldn't cause any issues. If the fixes above didn't work, can you pleaseu pload your config.yml file, which should be found in plugins/MinecraftManhunt/config.yml?
