All instances where World.SIZE is used were actually looking for this value, not the old one.
For example, the Load World dialog wouldn't let you input coordinates beyond 32 * 20 * 255 (top left corner of bottom-right-most cell, not bottom right), and bots would be prevented from actually entering the bottom-most and right-most cells.
I should note that the actual problem may be that 256 cells are generated in each direction when CELLCOUNT is 255. But meh. ¯\_(ツ)\/¯
