Mutator will not corrupt Fire Wyvern?

[Aser]

I have two fire wyvern, one male one female. Neither are on a mating cooldown or come out of cryo and have been out for weeks. I have the corrupt selected on the mutator and I have MORE than enough element in the mutator but the pulse will not trigger for either the male or female.

What do I need to do to corrput one? I just like the look.

any other mods that temper with dinos like CF, SF, better dinos ?

Make sure that function is enabled, I'm not sure if it is by default.

some functions in the mutator will not work on (Some?) wild dino's ... for example... the sex change function.. i had to breed baby Tek Rex's Before i could alter their sex with the mutator.
