Whenever somebody uses "plz"/"pls" it makes me picture them as Dolan... Essentialy meaning - all respect lost + prejudice regarding said person's intelligence.

Maybe someone Hacked the server. Sorry pal but either this:

1. Someone Hacked

and MAYBE try this:

2. Restart the Server, or start another world

Chunks reset/rearranged usually mean the server had a power failure and the world is corrupted. You could start a new one and MCEdit over your ship. That looks like a lot of work went into it.

Another thing that could have happened - Are you by chance running WorldEdit on your server? If so, I've noticed when I do large operations (regen, paste, etc) that sometimes surrounding blocks get modified. For example, I regenerated the ground level of one of my building areas and my below-ground storage area went from being smoothstone to having ores embedded in the walls.
