I found it by generating random worlds in creative mode in 1.12 this morning (June 7, 2017)
This island does NOT look like the mineatlas map. The map shows several islands close together, but in the 1.12 world I just created, there is only the one island that you spawn on. It's a pretty lonely island, with not much around it at all. The mineatlas map shows a couple of nearby ocean monuments, but in the live 1.12 map there aren't any ocean monuments there.
The seed is: 791039883381620
The screenshot is from above in creative.
I've just re-created it in survival mode to start playing it. If I discover anything else really cool about it, I'll post it in this thread.
That's because the Amidst and Mineatlas software doesn't always guess correctly on the world spawn location.
Ah, that explains it! Thanks.
It's turning out to be a really nice island. At first there were no animals at all, but while I was down setting up my deep branch mine one cow and three sheep spawned in. Later, another cow spawned, and a single chicken. However, while I was mining some wolves spawned in and killed all but one of my sheep, since I hadn't fenced them in yet.
I've flattened the top of the mountain and built a sea wall. I'm going to build a castle on the top flat area.
I built a nether portal and ended up on a shelf of soul sand, high above the surrounding territory, but as I stepped through I saw a fortress, just below, and a little ways off. It looks like there might be a blaze spawner within easy reach of the portal.
Also, while I was down below mining I had sheep, pigs, cows and chickens spawn, so I'm all set for livestock. The only "cheat" I've done so far is to visit another island to gather a few pieces of sugar cane. There wasn't any on the island, and I'm going to need it for the potion to cure zombie villagers eventually.
So i also found another island seed
its pretty nice
Oooo! That's a nice world. I explored it a little in creative, but I might try it in survival. There's a nice collection of little islands that could be turned into a whole network of bases and factories.
