Home Area Radius
Lets you modify the amount the home area expands by.
By default, when you have "Automatically expand the home area" enabled, the game puts a few (specifically, 4) cells of buffer around the object built. I’ve found that this is far too wide for my liking, especially when it came to fires.
This mod allows you to modify the amount of buffer the game uses when expanding the home area. You can even set it to 0 to have the home area expand to only the cells you build on!
