That option used to be in the config a while ago, it was taken out for some reason, (?) I always set it to false anyway as i dont mind where players set homes but i can see that it would be something some owners would want.
In my server, no TC, things start to decay. People also hide their TC, bc the moment someone gets ahold of it, they can of course build and so forth, but then they can break the ability to TP in and out. It adds another factor into raiding. Makes it a bit more of a challenge. :D (
VS being able to just put a "home" in the grass and never have to worry about someone ruining it. :D
