Building above the exit endportal will lure the dragon there to do his breath attack but as soon as u hit him once it will crash the game staying in a crashloop not beeing able to start the world again...further on endermen will attack the dragon and kill him without a player shooting 1 arrow or doing 1 swing can just sit afk in a hole,eat food and after like 15 minutes the dragon is dead
^dunno what this has to do with the enderdragon doing his breath attack but the crash is only mentioned by side in this report... this bugreport is about the actual crash wich theres no duplicate of. stop marking diffrent bugs as duplicates that have nothing to do with each other... if anything these 2 bugs are related but nowhere near the same thing
