oaky I'm going to the nursery in fallenclan because its says the achievement but when I got there, there were no kits at all. So I went back to my mate (Female) and she asked me to try kits. I think this is a little bug because if you play as a female and choose a male outside of our clan your kits will always spawn so I think this is a bug besides this is great!
(sorry I keep misspelling and asking you so much)
