I am new to the game and in learning I created a tribe. But now I want to disband that tribe. I go the the Tribe section where is says to Disband tribe and enter the name, but the button while it changed to a dark color does nothing to disband or delete the tribe. I am the only member in the tribe. I can't find anything that would allow me to leave and the Disband button doesn't work. Help! How do I get out of this?
