A few days ago my friend and I found the End Portal, so I proceeded to download the world. The EnderDragon got bugged by our fault, so we decided to upload the world we had dowloaded the day before. When attempting to upload the world, the progress bar loads all the way and then the gear to the left just keeps looping. This went on for 30 minutes. We decided to try and enter the world to see if it was only a visual glitch, but it was the same world from before we left the game.
So long story short:
I downloaded the world to my computer, and decided to reupload it (something went wrong and we tried to use it as a backup) but Aternos won't upload the world. What can I do now?
Sorry for my bad english. Thanks for your attention.
