Most people think when they find a village that the villagers and the village are completely useless. But the villagers do have one use which is quite valuable. Xp. I discovered this on accident when the villager wouldn't move and I killed him :D. I was lvl 3 at the time. I think. But anyway after I killed him I noticed I was lvl 8! That's the most xp a mob gives in the game, apart from the enderdragon, making villagers quite useful. So if you find any village in the mincraftian world and you think 'Oh stupid villages, they do nothing D:' then think again. Cause I would stop at any village you see and kill everyone. Of course because no-one would be there you could raid their houses as well...

I'll be posting a video soon to prove it.

Turns out this is some kind of glitch in the better than buildcraft callobration mod. Soz
