Far Lands disappearing and reappearing at every power or 2

[MiningBedrock]

When I spawned into a newly generated world to explore the far lands, I could see them at 128 blocks away for some reason, I did not offset or change the coordinate scale in any way. I explored them a bit and found 128 blocks farther than where they started it dropped off into normal terrain again. At 256 blocks further than that, they resumed, and at 256 farther, normal terrain resumed. It would keep going like this, doubling and the far lands disappearing and reappearing at every power of 2. The farther lands were not affected, i tried teleporting to 1073741824 and the farther lands were there, not normal terrain. I do not have a screenshot because I did not even think about posting this, for I did not have a GitHub account then. (my username is Mining Bedrock because I have a YouTube channel named that) (Corner Far Lands had the same repeating pattern)

What version of Minecraft are you using? I don't think anyone has had this problem.

1.12.2, as normal. How do you even offset terrain anyway in this mod? All of my other worlds spawned the far lands at 12,550,821, where they are supposed to be.
