Oh, I also have other mods in my world (such as enhanced biomes) could that possibly be the issue? Enhanced biomes has villages that spawn in the different biomes, but does that possibly stop the villagers and items from being spawned from your schematics in these different biomes?
I have a slight dilema. I have downloaded the schematics (I use world edit to put them in my single player world) but the villagers and items do not load... Is there any fix for this? I'd really love to be able to see the villagers and items.
