I can’t guarantee this is the reason, maybe @john can confirm it. But I believe the calculator only shows a link when there is available animals with matching traits.
Yes, but that was the problem, there was a 5 gene animal but no link for that combo in the results.
I’ve posted a screen shot of what I was getting, not sure if something has now been changed or if it was a temporary glitch though, as the results now show links for a lot of those combos with no link in the screenshot 🤷
