Despite some BoP biomes having specific village styles generate within them, along with their respective villager skins, any villager that is spawned in outside of inital world generation (such as through breeding, spawn eggs, or /summon) defaults to the Plains style, instead of the style of the villages within those biomes (i.e. Savanna for Outback, Taiga for Maple Woods, Desert for Xeric Shrubland).

This does not match vanilla behavior; in vanilla, all villagers match the biome's skin, regardless of how they're created; meanwhile in BoP, only the villagers that are spawned with the village during initial world generation match the biome-specific skin. This issue applies to zombie villagers as well.
