I was trying to find one on carno island, and it was painful. A 145 despawned, i tranqed a 135 which was devoured by saberthooths, a 125 picked a fight with an alpha rex, and the only argie whose level i didnt check before killing was a 140, after 30 minutes of nothing but <50. I finally was able to trap a 125 and was so relieved.
