Don't put it on a mountain, there's no room for the castle village! :(

Also, those huge mountain ranges seem a bit overdone, and it's all still quite buggy.. (especially with the lighting and chunk loading) but those new river/wetlands/grass plains/rain forest/swamp biomes are awesome though! but STILL NO VILLAGES/RUINS!

I've also tried to log in again with 1.7.3, but it says an error with the code: 503 for logging in on minecraft.net/game/joinserver.jsp.. does this mean they're patching right now?
