Just ruined my wonderful minecraft house :( Got it today, planning on setting up a server and playing with a mate. But anyway I started in a small valley with a lake, so I built a small cabin and dug into the mountain to start my mine. Also had a tunnel going straight through the mountain. Then I got an idea to seal off the lake. I decided to built a roof 5 blocks high sealing off the lake and adding a huge room for my use. And I finally did it but apparently all the monsters can still spawn inside it, might be because the game still recognises the lake as being outside :( but I took apart my door and front half of my cabin and then got swamped by creepers and skeletons :( Saddest face. May correct tomorrow, or just start over.
Anyway I’m off, might eat a little something to ease my hunger.
