Also, a word of warning for Spawntown, and everybody else, if there is a large concentration of villagers, you'll have a zombie siege even if the area is lit up. At least I think that's where the zombies came from, or they spawned on the treetops, not sure.
Oh yea, the golem that spawned and the second one that spawned don't seem to be attacking the zombies for some reason. Worked when I tested in singleplayer though.
