Fix: The /compass start <point> command would throw an exception if a point in another world was selected as the destination. This is no longer an issue and the Compass will simply not start if an unreachable point is selected. The GPS commands remain unchanged as they were unaffected.
Revised: A few of the compass commands have been restructured during the previews fix. This should make it more firm as well as hopefully make it easier to introduce interdimensional world links in the near future.
