I’ve been having this issue with all savage wilds animals (why did I even waste my money on that dlc funcom) rhinos, greater shale backs, the dogs on isle of siptah
Probably other stuff I’m not thinking of.
This bug has been reported 4 years ago already. I had a rhino too which became invisible after the Age of War update. Most wild dogs and coyotes are invisible. Lots of elephants are invisible. Even Valeria is partially transparent. This always bothered me greatly as it takes away from the game experience. But after the stability fix I cannot even play the game anymore due to my character freezing in place.
Just a heads up, fought the blood crystal golem in the unnamed city near the red mother and it’s not only invisible, but can’t be harvested either. On PlayStation. Did it twice, same issue both times.
