So, in this one world my world has very slow framerate on a decent PC. This has happened before, but this was years ago! My framerate is unlimited, I tried redownloading, I looked for other forums but most of them were outdated. My multiplayer is fine, but my Singleplayer world is broken. Any ways to fix it? I only have two worlds.. Thanks!
**EDIT**: My problem is fixed, it is because of an accidental modification in the seed.
