This inbreeding fix from Amaikokonut's blog looked like a great idea, so I tried to apply it in a tweaked genome I'm playing with.

Problem is, a whole wolfling run of norns with the anti-inbreeding genes failed to breed before dying of old age- they left only one generation 2 baby. I hadn't made any other changes to the reproductive genes, so on a hunch I hatched a couple of the altered norns, aged them up to adult and stuck hoverdocs on them to look at the fertility graphs and- Well.

They seem to be spiking libido lowerer when they look at any norn, even though all being first gens they're definitely not related.

I double-checked though, and I input everything correctly- the "don't breed with siblings" gene matches the one on Amaikokonut's blog. The only difference was that it was at the bottom of the genome, but moving it up to the gonad organ didn't make any difference I could see- they still got dosed up with libido lowerer if they looked at another norn.

What could be going wrong here?

(Yes, I know about CFE Family. I looked at it with genecompare a while back though, and it alters the brain structure beyond what the CFE edits already do- so they wouldn't breed safely with non-CFE Family norns. A more hybrid-compatible approach would fit my playing style better.)
