Please note that I have now redone all the maps and they now point in the right direction, including the lot locations for both worlguard regions and towny lots. So the sun now rises in the east and sets in the west.
There is now also a command /compass which will tell you where you are looking. The questionnaires for settlers etc are now also updated. If you find anything that is still wrong, please let me know.
The only glitch is that the lot A1 is now in the south-west instead of the north-west but I guess we can live with that.
