I tried re-creating the world and the ocean village did not show up. I made it a few days ago, and use the latest snapshots, I tried pre 4, 5, 6, and 7, but the village did not show up in any of them. Here are screenshots of the original world, and I promise that I did not build anything in the pictures. I suppose it was a glitch?
I swam to the island to the south and got the trees, transplanted them to the main island, and it is working out very well. I am enjoying this seed very much, I just wish that the ocean village spawned for everyone else. =/
