We run a custom modded map called Structe Island and have buildable area's such as some icebergs and caves etc however when the player tries to add a home it gives them the error that it's too close to a monument. I've gone through the config files which are tailored to our server and have both caves and icebergs set to true however both aren't working properly. Is there a way that I can solve this issue either with the plugin itself or by editing the map?

(Edit: We also do not want to allow players to set homes at all monuments to enabling that is a no go)
