*Created by: Barteks2x* Random lines of chunks are not populated. The issue is [here](https://github.com/Barteks2x/chunkgen/blob/eb01234e0e0d7050b4196441777415bbe9381a28/src/main/java/com/gecgooden/chunkgen/util/Utilities.java#L36). As I explaied in my comment to issue #2, you need to generate chunks at (x, z), (x+1, z), (x, z+1), (x+1, z+1). In any order. The order doesn't matter because if you, for example, generate chunk at (x+1, z) it will also try to populate chunks at (x+1-1, z), (x+1, z-1), (x+1-1, z-1). Your way mostly works because you don't explictly unload chunks. And apparently forge unloads them automatically. And when forge unloads chunks - some newly generated chunks won't be populated.
