Problem description:
So I seem to be having a problem with my map where, an icon file larger than 32x32 doesn't seem to want to remain on screen once it's anchor point moves off screen by 6 tiles is seems. So if I make something that's say... 7 tiles wide, it disappears from the screen before it moves entirely off the side of the screen.

Is there any way to avoid this besides cutting up the images?

What you're describing is unfortunately a bug. The linked thread has a few suggested workarounds.
Well damn. Guess I don't have a choice then.
