I do not know why, but in the world "Warp", In the mine of ores, when users try to undermine a block that has been configured to protect an area, they can not ...

I tried to give myself a user rank and give me the permission: Protectionstones.* because I thought that maybe it was a permit, I tried, and it did not work.

I put /rg list and in the world "Warp" there was no region of protection.

If anyone knows the answer to this problem, answer me :D
