Deadly Prey works on yellow beasts

Hello

i have noticed that the Atlas passive "Deadly Prey" states that Red Beasts can escape with a 50% chance, but a lot of times Yellow Beasts escape the capture.
It is nice to have more stacks of Hunter's Cunning. Is this written wrong or what happend there?

I also agree that this is a bug. Yellow beasts in my map have been breaking out of einhars chains. I have not tested it without but I have the notable allocated that converts yellow beasts to red beasts.

I'm wondering if Hunter's cunning isn't bugged too, because as I gained more stacks, the others beasts started dealing increasing amounts of damage to me, even those that had no stack of Bestial Rage on them.

I was killing the beasts easily at the beginning of the map, but after killing a beast that had 11 stacks of bestial rage, I jumped to 14 Hunter's cunning and I noticed that the final beast (who had no bestial Rage) was taking very low damage while I was taking a ton.
