@Bryndan W. Meyerholt (BWM) thank you for your words and for looking so close. I could not find the hole alone, but I covered the only spot I would suspect of being “leaky”.
@Cyan Blue - You already have several characters using 45° diagonal strokes with X & x as the basis. I'm certain you could derive a multiplication symbol from those! ;^)
I'm using Windows, but because FontStruct app use Lucida font, I make font sometimes can be mistake as cedilla instead of comma (in Latin Extended A and B)
Top pick?
