In the rule “The City and Neighborhoods” change the text

When a Kaiju God goes idle, no changes will need to be made in The City document to reflect this.

to

When a Kaiju God goes idle, and that Kaiju God does not have an empty neighborhood named after them (i.e. they renamed a neighborhood and populated it.), no changes will need to be made in The City document to reflect this. If they do have an empty neighborhood named after them (i.e. they had one made for them but never named it), remove this neighborhood from The City document.

This will keep it clean from someone never naming their document and allowing for someone who joins later to have their own to name.

When this passes, if any Kaiju God has gone idle from the start of this dynasty till when this passes, and there is an empty neighborhood named after them, remove it from The City document.
