@Pila: Wow, I'm embarrassed to admit it, but you're right. At least about 10-20-10 being a possibility (for some reason I was convinced that row had to be 16-8-16). I followed that trail and eventually the puzzle broke, so I believe there was always a unique solution, but it was definitely harder to find than I intended.
I added a white dot, which should help things. Thanks for letting me know!
