Soo... I just got the Xbox version of this and I've been trying to figure this out on my own but the answer has not been forthcoming. How am I supposed to keep monsters from spawning INSIDE my fortifications? Last night I went to bed and woke up with a creeper next to me which exploded and destroyed my chest with almost all of my valuable equipment in it, and right as I was getting a handle on remaking the chest, another one shows up and destroys all the items laying on the floor. I was so pissed I reloaded my previous save (which was about 3 hours previous), and quit for the night.
