Since I got the 14w26c snapshot, my worlds have been really strange. For example, blocks were missing, paintings had fallen off the walls, and this messed alot of my builds up.

If this was opened in 14w26a or b then read this:
"You have to use a backup of your world that was never opened with 14w26a or 14w26b, otherwise opening the world save in 14w26c will destroy most of the chunks in your saved world.
Never use snapshots without making a backup of your saved worlds first."
From the snapshot post.
Did you update from 14w26a or b?
