The villager_v2 mob cannot spawn in template worlds. This was in the 1.11.1 changelog. I was trying to redesign the Mineville Highschool Role-play map, and I wanted to add a villager_v2 in the library. But nooooo, 1.11.1 just HAD to make the villager V1 spawn instead, villager_v2 completely nonexistent. I even tried /summon. 

I know that you made it where villagers won't change to villager_v2s on template worlds for a reason (not to mess up add-ons). But please, AT LEAST let me /summon a villager_v2 on my own world.

UPDATE: Dear Mojang, thanks a lot for listening. Not only can you now spawn villager_v2 on the Mineville Highschool Role-play map, but there is a new updated taiga village near the school!
