Basically, there's a new feature in 14w32a that allows users to summon entities that can't attack or move (/summon [entity name] ~ ~ ~

). Not sure if this was a secret thing, but that doesn't matter. The bug is that if you summon an Ender Dragon with no AI, it has AI and moves around. I'm assuming this is because of how it was programmed (crashing into stuff, breaking blocks) but either way it's a bug, and bugs need to be squashed. Thanks for tuning in!
