Okay so basically, I made this world in 1.17. After that, I stopped working on it for a while. Then, the 1.18 update happened and changed world generation completely. As a result, my world got corrupted and was overwritten by the 1.18 generation. The landmas that I was on became an island, the giant grey square I made (for putting on a map) became a victim ofbiome blending, and the bottum of what was probably a 1.17 river was now part of the new ocean floor. Not only that, but the seed that generated over it was INSANE! What's the seed number, you ask? 666. Yeah, I used it as a joke. Turns out, it's a lucky seed. So... Is this the work of the devil, or? Whatever, I pretty much struck jackpot with this.
