Fix loading templates in new z-levels being off by one turf (#54135)
Fix loading templates in new z-levels being off by one turf (#54135)

Due to how byond maps start at 1,1 and not 0,0 when loading a map that 
is the same size as the world the map will start loading at 0,0 in the 
world which is outside the map. load_map defaults the x and y offsets 
to 1 for a reason!

Though you can load a map that is larger (257 x 257) than the world as 
a band aid for issue.
