make sure to put a roof over it, because it takes ~5 minutes to cure a zombie. the sun can easily rise in that time and if the villager is still in zombie form they will burn. the worst is when you have a zombie villager following you but you don't have a trap set, and it is POSSIBLE to dig a trap on the fly, it's really stressful and mistakes
Stranded is a Gamemode where the player can only travel between their β£ Private Island and β£ The Garden. Additionally, Stranded profiles are similar to β² Ironman profiles in that they do not allow Trading with players outside of the Co-op, they use the Special Bazaar, and the Auction House cannot be accessed. Stranded profiles can be played Solo or as a Co-op. Players on StrandedYou'll first have to create an artificial island, first for a place that mobs can spawn and to "save" the zombie villagers, and then afterward for your future village. Sadly there isn't an option to create a "real" NPC village underwater, but for an artificial island city, the possibility is there.
The answer is way simpler now you can now make mobs FULLY invincible. Here's how: /summon Cow ~0 ~0 ~0 {Invulnerable:1} Easy! If you want to spawn any other mob, just change the "Cow" to the name of whatever mob you like. If you were to spawn a zombie, the zombie will still burn in daylight but will not take any damage from it. N1uGn.
