Well, the other day I opened up a single player world, and after around 10 hours of playing, I haven't seen one sheep. Not that I need sheep, I can always use string and dyes, but a couple sheep would be nice. Is this happening to anyone else, or am I just stupid? I've been playing since the Halloween 1.3 Beta update and I have never noticed peaceful mobs not spawning before. I have one mod installed, toomanyitems.
THE ISSUE HAS BEEN SOLVED
