So I just had two lionesses give birth and last time I checked, I had five lions with mutations, one of them being a primal cub and the other four being adults. Mutie cubs don’t appear in the mutation overview, and I knew at the time exactly which missing lion was mutated

I saw my mutation overview and it says I have SIX mutated lions and when I checked all my cubs, there were no new muties??? Am I blind?? Or is this a glitch??
