Saving entity NBT (possibly the player NBT)

After updating my world to the newest snapshot, I experienced a crash after about 5 minutes. Loading again the crash happened quicker.  The world saved, and as far as I am aware there are no corruptions on the world file.

Provided below is the crash report:

java.lang.IllegalStateException: Value -1 outside of range [0:127]

Edit: Upon further experimentation, the game also crashes when I exit the world.
