I can confirm that copyspr seems to be just as bad as using new sprites, even if you are copyspr-ing a vanilla unit.

Mine and Sombre's mods contain a set of new units which copystats vanilla pretenders and then make them available for the nation. Removing this section improves the sprnbr situation. I've just managed to make my mod for Marmoset work by doing that.
