Hmm, that smells fishy. I think I have an idea. The local chunks in the
SimpleTextureMaterial are added after the chunks from the ChunkMaterial.
Given that you use units 1 and 2, 0 should be free and used. Turns out:
not so. There was a bug in the SimpleMaterial/SimpleTexturedMaterial
about handling of chunks. Should be fixed now.

That's always a possibility. Like in this case. Thanks for spotting
it. ;)
Thanks
