I was trying to fight the ender dragon, as most players try to do, when I was instead thrown in the end city realm instead of the normal End. At first I was happy I was gonna defeat it, but i was somewhere far away from the dragon and instead spawned in an end city biome. There were no exit portals because I have not defeated the ender dragon. I had to give up my achievements and /kill myself in order for me to respawn and try to test my theory. I am sad I had to give up my achievements because of a dumb bug. Mojang please resolve this horrible issue because im the only player that has been teleported to the end city instead of the end. And yes I did do research on how this bug occured and there was no information.
