Upon entering the End from the Stronghold, the "arena" where you fight the Ender Dragon does not generate correctly. There seems to be missing blocks in the middle and around the outside. Not really a big deal, it's still possible to defeat the dragon, except that the portal that has the Egg in the middle generated below Y-0.

The area where the portal normally appears once the dragon is defeated is below where it's possible for the portal to spawn. So basically, it's impossible to leave the End without jumping into the Void to my death.

I've deleted my End save data and the results are the same. Seed number is 3761987256467393916 if that helps.
