Awhile back, we had that update that limited the amount of mobs in a certain area. I believe it was also said that hostile mobs can spawn in any light level at night. I never really noticed, until I made my SMP8 wild camp. The mobs out there are off the charts, no matter how good I light it up. Proof of this? I saw a Creeper spawn in my town, which was fully lit up. Now, I know, i'm saying that one of Aikar's things isn't that great, its weird, I know, but I think this is stupid. I know this might have been put in to make up for the decreased mobs, but this could have been done a little better. This is what I think, don't torch me because of it.
