I started a brand new map on 1.0 on my bukkit server (using the latest bukkit RB) but have noticed a few problems. When entering the nether, the blaze spawners don't seem to spawn anything. I've found the spawners, waited and nothing spawned. When using a mob spawner plugin, they don't appear either. In my normal world, i've not seen any endermen at all. I've covered a fair few chunks and nothing. Also when using the mob spawner plugin, they say they've spawned, but don't appear like the blazes. Is this a known bug? It's annoying as I would like to use potions legitly, but without blaze rods, I can't even make the stand lol.
