Having a bit of an issue with the block cave function. I have it set to block teleport in caves but players above ground near the caves are effected by it if its not set to a small distance like 20, which doesn't cover the entire cave. Could the height of the block somehow be changed? Players are able to build no problem and only find out they can't set home when its too late.
Can't teleport or set home above ground when near cave
There was an update today that addresses this issue. See related thread.
