Is there a way to find a specific biome using a Win 10 MC seed of an already generated world? I know for the java version there are tools online like Amidst and Biome finder which do that. In my main Win 10 world I have found every biome apart from a mesa and would love to locate one. It's not through lack of looking!
There are Mesas, that's for sure. You can find seeds for them on this forum. But there are certainly seeds where you can travel 10,000 blocks and only see forest variants and some plains, a swamp if you're lucky. Those are super frustrating!
