World has shrunk to only 255 by 111blocks. Unable to move further in any x or y direction but cab move down to zero blocks and up to 255.

After a week of frequent disconnects, unable to log on, and not saving changes to the realm. today the size of the realm has shrunk to 255 blocks by 111 blocks. Up and down directions is unaffected. I also cannot teleport outside of this area or back to the original spawn point
