I've seen a couple of bug reports on this issue on the official Mojang Issue Tracker website https://bugs.mojang.com/browse/MC-98277 but this is something different. Most of the time, when I create a new world, the chunks within a certain radius that spawn around me are displaced. These chunks still belong to the biome where they were created (e.g, a chunk created that's part of a ocean that then appears in a desert will still have the characteristics of a ocean biome, like rain and sky color.) This happens without any changes to the world, no log output errors occur (and seems to intensify when Biomes O' Plenty is active), it just happens and I have no idea why this keeps happening. I wonder if there is a workaround for this issue since Mojang considers it resolved. See the attached pictures for examples of this bug.

First off, start by removing your mods, esp core mods.

And then see if you can reproduce this and if so provide the seed so I can take a look. Because This is the first time i've heard of this.

Steps to reproduce:
1. put render distance at 32

2. Create world with seed: 1745855786

3. go to the center of the world: 0 150 0
4. place a command block at the cords given at 3

5. insert this code and let it run in the command block for 30 minutes

This is what I found during my test run

You might want to take a look at this too...

Many people have been experiencing this since 1.8.1 up till now and even in future versions if this issue doesn't get resolved.
