I entered the end with minimal stuff to build a safe bridge to the main island. I died a little early but when I returned to finish my bridge, a second ender dragon health bar popped up as I approached the main island and there was another ender dragon. I made a copy of my world before entering the end and the problem is replicable in the copied world. The seed is 1442774710 and the stronghold portal coordinates are 807, 41, 1636. Please fix this- all my achievements are in this world but I can't kill 2 ender dragons at the same time!
