Regression: Sprite issue with vertical maps

This was fixed in earlier 4.x dev branch, but now with 4.1 it is broken again.

When on a vertical map, if you move up or down on the map, then any sprites that scroll off the map, suddenly appear on the opposite side. So, if you move up, any sprites that go off bottom of map, appear at top. If you move down, any sprites that go off top of map, appear at bottom.

Previously this was fixed with sprite refresh settings, but this fix no longer works.
