Well thats end of the list. Hope you will enjoy the map. (VILLAGES WILL GET BIGGER BY SOME TIME BECAUSE OF MILLENAIRE MOD, VILLAGERS ARE JOINING VILLAGE AND BUILDING NEW HOUSES SO...)
also don't use command /time set, because it may break Millenaire because they are very functional and they also sleep when its night.
