The sloth doesn’t seem to be spawning like a common should, or even a rare! I kept track of some of the creatures and in a 30 minute period of driving through neighborhoods this morning I saw:
2 Eremotherium (Sloth)
I counted only creatures within my shooting range and I had a mega scent running. One sloth was from the scent and the other was waiting for me when I came up on it.
I started when game time hit dawn and was in Local 3 the entire time, as evidenced by the Lythronax and Delta.
