Tool/MMAP: Fixed invalid check causing certain tiles not to build (#27833)

example: mmaps_generator 230 will cause tile 33, 29 to not build because of the check. causing NPCs to not have mmap information in some parts of the map.

.go xyz 1380 -831 -88 230 has no mmap tile information because of above check.
