Ill just open a new mine then... How can I know that it will not happen with my new mine too? How can I know that someone will not just come and "buy" my mine? :/

So I need to talk with him and ask for permmision to mine in this spot?

it says "lakeside"

Hi, I have digged a deep mine near my house a few days ago. When I came back down to continue mining today whenever I try to break a block it wont break and tells me I don't have permmision for this area. Why is that? Thanks.

Thanks for your help Ghost, found a 1.2.3 minecraft jar file on the internet and replaced the 1.2.4 one that i had with him.
