Ok, I'll recheck the third seed again. But I proved that was true about structures in the "Forest Glade" Seed. So in Caves & Cliffs Version Part 1 we used the "Forest Glade" Seed as a Bedrock Edition Trial Seed. But in Part 2, although the seed is the same as in 1.11, the world generation isn't the same because it's turned into the Tundra-like biome spawning, and later as 1193926712.
