I was checking on my pronghorn when I noticed a couple of the albinos were a very odd mottled color. I tried moving them within the enclosure and they "snapped" back to white. I created a ticket if anyone else has seen this.
Absolutely agree with this. Doesn't seem to be a Bug at all.
But if it turns out to be a Bug, I recommend to verify the Game Files (helped when I've had a Bug once that made the Fences purple)
