Dryo and Galli as carnivore Feeder Food... Need Guidance

I want to fed the carnivores Dryo and Galli instead of goat and cow. I have seen you tube video of people doing that n I have fund 3 posts also. But for some reason, I cant apply that in my game. Everytime I am trying, the game crashes while disposing the food. All I am able to do is to change the name of the food items in the carnivore feeders in Dryosaurus and Gallimimus instead of Goat and Cow. Can someone who using this please guide me in details like what files needed to be modified and how ? Or someone can provide a download link please ... Any help is appropriated. thanks anyway.

I've had the same problem trying to do the same thing. The problem is, you need to have the dig sites of Galli and Dryo unlocked before you can dispense them from the carn feeder.
