If I remember correctly it used to be that a minehole couldnt be built above a personal claim or village claim (if everything was mined out).
My question is, is that still true, if there is a village on a large cave area on lvl 1 but no claims/walls above it, can someone put a minehole down into the center of the level one village or does it act like it used to, saying something like that area is blocked?
