Here is my idea.

When you make a claim it will automatically extend your claim all the way to the sky limit and all the way to bedrock. This will prevent players from tunneling underneath your claims.

With the way things are currently with claiming you need to go down to bedrock and place a block in each claim you make to extend the claim downward. This is not known bye many players so they find tunnels etc all around and under their claims.

I found some players had done that to my base and they even bragged about it with a sign saying “If you didn’t find this you would have never known”.

In short we need to get claims to go all the way to bedrock.
