I went into the end shortly after opening portal because the kids wanted to see the Ender Dragon, died. Came back and decided to slowly take out Ender Crystals to make the Ender Dragon fight more manageable because the kids wanted to help fight. Died a few times. Came back and TWO dragons were there. Figured it might just be a bug and would work itself out. A week or so passed and Kids have been building in the world. I go back into the End and TWO dragons are still there.
Two Dragons will be impossible for my 6 and 8 year olds to fight and rolling back server is out of the question because of the hours of building and work put into after the initial discovery.

NEED a fix for a gamebreaking issue.
