Hi, I am new to this so I don't know what info is needed here. If you ask, I'll do my best to find it. I was playing on a single player world for a while, when I needed to move my player using MCEdit. However, since I have done that it has made the world unplayable, stuck on the "Downloading Terrain" screen when loading it up. Thanks very much anyone who contributes, I am clueless.
