Some chunks not populated

[Barteks2x]

Random lines of chunks are not populated. The issue is here. 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.

I have changed the chunks loaded to the ones you specified, and the test version is here: https://dl.dropboxusercontent.com/u/6295002/chunkgen-1.7.10-1.2.2.jar
It looks like it works to me, can you test and make sure it does for you?

It still doesn't seem to work correctly (tested with mcedit, generated 50x50 area). I decompiled the .jar file and I think I know why it dtill doesn't work correctly.
Before loading chunk you are checking if it's already loaded. But you only check if (x, z) is loaded, and then if it's not - generate chunks at (x+1, z), (x, z+1) and (x+1, z+1). So when you generate next chunk, (x+1, z), it will be already loaded. So it won't generate it again. And it won't generate chunks for population. The fix is to check existance of each chunk separately.

Ah, thats what I get for hastily coding..
This should do it: https://dl.dropboxusercontent.com/u/6295002/chunkgen-1.7.10-1.2.2b.jar

Works perfectly.
