Zombies spawning right next to players in FTB Monster?!

A couple of times now I've been out and about at night in the Overworld, beating up on a zombie or two, and had new zombies spawn RIGHT NEXT TO ME. Literally in striking distance.

I thought this was impossible; that Minecraft wouldn't spawn hostile mobs closer than ~20 blocks to the player. Anyway, it made things a little exciting. I really REALLY hope it's only zombies; the implications of having creepers spawn right on top of me are not pleasant to contemplate.

This is a vanilla mechanic. When fighting zombies, there is a chance that they will spawn more, most likely right behind you.
The "new" zombies can be normal zombies, or baby zombies, and if you have a mod that tweaks the mob difficulty, it will affect those zombies as well.

Aha! Thanks very much; I didn't know Minecraft had buffed zombie hordes to this extent. OTOH, hooray indeed now that there are fun uses for rotten flesh...

Leather from redstone furnaces, zombie jerky with drying racks.. blocks of flesh for golems (or just decoration, you sick and twisted person you...)
