So I am making a prison server and I have some trouble with worldguard. First, I made a mine and made the whole mine as one region. I set a flag so nobody can build. Then, I made the actual mine a region and set it so people can build. No matter what I do players cant build. I even made c-mine, the actual mine region, the parent of c-stonemine, the actual mine itself, the child but it didnt work. How can I make it so players can build in the mine?
