Currently experiencing difficulties finishing the fight with the Ender Guardian because he appears to have some sort of leap attack ability that ends up putting him on the next level of the dungeon above where he is currently at. This is fine for the first couple of times he does it, because he is on the third floor down in the dungeon, but once he does a leap attack that would place him outside of the structure he disappears. The first time this happened, I flew around for a minute looking for him, and when I went back to his original room he had returned there. The second time, however, he has disappeared, and even though the boss bar is still on the screen, he is nowhere to be found. I've looked through the whole structure again on all levels, and on the island surrounding the structure but cannot find any trace of him.
