Hey @sidekickmatt! Have you joined Terracore's discord server yet?
Here is the link: https://discord.gg/V9B6DKaQCC
Once, you're in there, go to bugs-support and open up a ticket informing about your problem with the citizenship fee. @crypt0gnome, terracore's dev, would help you with your concern.
Anyways, as a player of Terracore, I am sorry to hear that you experienced this and more than thankful for understanding. Good Luck!
