Could you attach your plugins/TARDIS/config.yml (before editing!) to this issue please

The switch_resource_packs config option should be in planets.yml, and not in the config so:

• Open plugins/TARDIS/config.yml
• Find the switch_resource_packs config option
• Delete that whole line
• Save the file
• Restart the server

I'll add a check for old config options and remove them if they're present (which I usually do, but I must have missed that one...) having your unedited config file will help :)

That makes a lot of sense! I just did a version 1.16.5 to 1.17.1 upgrade of my server. Much appreciated for all the work you do with this mod. I have been an avid user of it for years. Attached below is a copy of my config. This server has been around since 1.14 so I have been through a few upgrades.
