I believe that the super cinnamon/black pastels also have a tendency to kink along with the duck bill thing.
With caramel there was a thread questioning if female caramels can produce good eggs. I've heard 2nd hand that at least one breeder reports getting good eggs but there where also several examples of no good eggs from caramel females. If there even is an actual tendency for female caramels to lay bad eggs I'm wondering if whatever lets some breeders avoid the kinks also allows the females to produce good eggs .
For any new morph including supers of co-doms I wouldn't assume that both genders can reproduce until it's proven. Hopefully our favorite mutations are only skin deep but problems eventually surfaced with some older mutations so it could take a while to hear about any problems with the newer mutations.
Spiders may be homozygous lethal like the woma (whichever kind of woma produces pearl, recently there are reported to be two different mutations called woma). If true, it would only come into play when breeding spider X spider. I also very recently read that the spider and sable combo might be lethal.
One of my females produced a clutch on breeding loan with several small and missing eyes. It wasn’t limited to a morph and the parents weren’t related so I don't know what caused it but perhaps something about the incubation or development environment.
