Getting the same message with an Eternal Alpha Indominus Rex on Ark Eternal. Very disappointing since it was the first Eternal Alpha we ran into in our playthrough with Eternal and Genomes together.

Maybe it's just because Indominus Rex isn't a default Ark dino to begin with so fluky? But I've seen Dragons and such done too so perhaps just an update.
Loving the mod otherwise though :D Except for the occasional infinite tower fight ;P


Update: So after we evolved the Eternal Alpha into a Prime, it decided it wanted to work with us after that :) We now have an Enhanced Prime Indominus Rex.

i think it in just that it is too big for even the biggest genome enhancer because the new tameble dodoreaper "nova the detroyer" wont work either
