any suggestions on what the "something" might be?

Hello, I hope I am not posting out of place, if I am, I apologies now. I am working on my first mod, which I will leave the details about it out. I have come up against a small problem today, this morning the mod was all working fine. The issue is that when blocks are harvested they're dropping tiles (of the block with correct texture) instead of the nicely rendered cube, as I said this was working fine this morning, the only thing we altered was the spawning algorithm, then BAM! it started going crazy on me. I have reverted my spawning code back to how it was this morning, but it does not seem to have fixed it. If anyone is feeling particularly generous then I would appreciate a critical eye on my code. Thanks in advance! Naturally a large bulk of the code has been omitted, more because it is not relevant to the issue. Thanks again.
