There is a zombie somewhere in my base. I've literally dug out every direction, and cannot find the zom. It is a constant digging noise that I cannot stop. Is there some sort of command to kill all zombies near my base? The mob is obviously glitched and "not real". I went into creative mode and literally blewup the entire area with rockets and dynamite. But I still hear the zom digging and making noises. I guess start a new game?
