Minecraft 1.18 introduced world blending into the game. As far as I know, Old World Types shouldn't recieve 1.18 world blending. If you have any Old World Types generated before 1.18 They are do not do world blending. But when 1.18.2 was introduced Old World Types get world blending which resulted in my 6 year old world looking like a bomb hit it. The screenshot was taken in Minecraft For Android, but it is the same world with same Structures on the Nintendo Switch and the exact same issues are the Nintendo Switch. I would like to be a way for this world to not have 1.18 world blending, because even backups suffer the same blending on Old World Types. Thank you for your time and dedication to reading this bug report.
