I was playing in the End on realms, trying to kill the dragon. I died a few times but something was off. When I was about to re-enter the end there was a sudden lag spike. I went back to the end to see that the dragon was somehow re-summoned. And I was faced with fighting not one but 2 dragons at once. Which has proved to be nearly impossible as whenever one stops attacking, the other begins attacking. This is even harder considering the difficulty is on hard and the end crystals all appear to have been replaced. Typically the dragon isn't too big of a deal once you have good enough armor. But now even running in the end for more than a few moments seems to be an impossible task. This is excluding endermen because I entered the end wearing a pumpkin.
