Fix a few chunk errors
This does not fix chunks on its own, they're still very much a work in progress, however this commit should hopefully resolve a few issues. The client might still crash due to some invalid mappings (most likely), but this should bring us one step closer. With hardcoded values for the chunks, the client wouldn't crash (which leads me to the conclusion stated above) and on the occasions that it would not time out, the chunks were empty.
