I have found the cause of the problem! (Level Loading Problem)

The problem is the map. Somehow, the map has everything to do with not being able to change levels. I don't know exactly what the problem is, but I do know that the map is the cause of it. I completely reinstalled Graal and was fine the first time I connected to my server, but then when I closed Graal and reconnected, the map had downloaded, so it didnt work again.
