I have just discovered that a zombie villager can be cured and returned to a village. Now, I have surface zombie dungeon in the soup region which i am currently terraforming into a multi biome. If anyone would like to assist me in the healing of naturally spawned zombie villagers and there transport to a custom village I would greatly appreciate the help and others would be able to freely trade with the villagers.
To heal a zombie villager you need to use (splash potion weakness) followed by golden apple.
Thanks. Beergogles
