In my current SMP world (1.9 pre), we have eagerly been looking for snow biomes. No luck so far, despite some wide-ranging expeditions.
Question 1: We generated this world in the 1.8 pre-release, where no snow biomes were created. I had thought, however, that with later updates these biomes (along with giant mushroom ones) would start to appear when exploring new chunks. Is this correct? Or is our 1.8 world forever alone snowless?
Question 2: If my initial assumption was correct, and there ARE snow biomes somewhere in this world and are just really far away: Is it possible to view a map of a certain seed, without exploring it? I know I can export a map of the known world with MCMap etc., but is it possible to view unexplored chunks within a certain distance from the spawn, for example?
