@SymbioticDesign Thank you very much! 

Oddly enough, I don't think it was the tri-linear quarter turn.  The end of the G that was wrong was actually the solid eighth turn on the right at the top of the solid section, and I may have these other block types wrong, but the others I believe were the top-left part of the 1 that is now a tri-linear stopper (where one line stops and the outer two join together) and one or both of the ends of the 3 where there is now an eighth turn.  All the other tiles, tri-linear quarter turns included, seemed fine.  I solved it by simply going back, deleting those tiles and adding my desired one again.  I always notice Fontstruct seems to do this often, and randomly too.  I was making a font using lots of solid square tiles once, and they all changed into solid diagonal-half tiles when I went out of the editor!  

Also, thanks for the feedback about the K/k and the Q/q.  Those were some of the letters I was actually a bit fussed about because I didn't know how to do where there are now those weird, complicated curves without it looking off.
