missing limbs?

[Skidez]

NOTE: just an idea

so in niche one of the basics is to not inbreed, and if you do the baby could has blind eyes or be sick. but what if a baby could be born with a missing limb, a little stub where a front leg would be. it doesnt have any abillities, all it does is block you from having another paw for more abilities. tell me if theres any flaws.

Actually, this would be a good idea to deter you from inbreeding, like with sickly nichelings! So, instead of a deformed paw, you could get like the model of a deformed paw and deactivate the paw gene, like you do with the inactive ones. So you'd still retain the actual gene? Idk, just thoughts.

The Deformed paw works like this, but possibly it could be for the hind legs.
