So I've been having an issue recently with the way my world has been generating unexplored areas of the map. The borders of biomes with different average y-values don't seem to be smoothing, and instead produce flat sections of cliffs along the borders. This hasn't always happened, and I've been occasionally adding mods as I go, so it seems like this is some kind of conflict between mods affecting world-gen. This isn't something that happens with every biome, and it seems almost random where it happens. While this can look pretty cool, it does also just look buggy. I've already explored most of the area around my base, so most of this is happening a ways away from it. I'm mostly just asking about this out curiosity, since it isn't the biggest problem. Any suggestions?

That is the issue, when you add a mod that effects world gen, especially the biome layer, you're going to run into these sharp edges.

They are between old chunks that were generated before you changed the mods, and new chunks.

There isn't anything you can do about this. Maybe go through your old world prune it down to just the things you want, and live with the border/manually make them nice after you stabilize your modpack.

That's what I figured. Ah well, I can live with it. Thanks for the explanation.
