That's the Classic CompositionGen's fault, it doesn't handle biomes, it only knows that terrain with height similar to sealevel should get sand instead of dirt / grass.
I'll be working on a Biomal CompositionGen after we fix the "too many packets" bug.
You know, the version I accidentally sent to you was the old composable_generator branch, so it was around Rev 503, and you still managed to produce the bug. So it's been there for quite some time
I'm working on a more detailed log now, when I finish it, I will upload a version for you to test again.
