On Minecraft Realms, in the End, I had summoned the Ender Dragon, twice. This was all in version 1.9. Of course, I did not know that the AI of the dragon was bugged, and now I want to remove the Ender Dragon.
I tried using the commands
/kill @e[type=EnderDragon,r=100] and
/kill @e[type=EnderDragon], but alas, it did not work.
How do I remove the bugged Ender Dragon, in Minecraft Realms?
