#How to allow only deputies/leader to start village fair challenge.
lyric sand
First, go to the village fair event and click on the "select a challenge" button.
Now you have to click on any challenge and a settings button will appear to the left of the start button.
If you are the cooperative leader, you can now change the settings to determine who can start village fair challenges and if there are delays in starting them
