Chunks not loading.

I am creating a creative world on Minecraft 1.8. I noticed a specific chunk not loading at all. The blocks inside it are invisible and I, the player, get stuck inside the specific chunk. I tried loading the chunk with other versions like 1.7.5, 1.7.10 and the chunk will still not load. I tried saving & quitting inside the chunk and the whole world is blank with a new biome "plains" when I join the game (the original biome is Desert).
