After chatting with Jug, I did a little investigation and solved the mystery.
From level 1951 to 2000, the range when he was hunting, there are only 4 commons, 4 rare, and 4 unique items that he can breakdown. So it made a lot of sense that he got low auto-fragment count.
Thanks everyone for the reply. I double checked all my settings before posted here. Maybe it was pure bad luck but I have never seen 0 drops in 15 minutes time frame with 1,400,000.
The Hunted Cow Titan has had a higher spawn rate for a good while now. And there are a lot of pails in the game already. Prices have plummeted and I don't know if many others will agree but I think it's time this titan's spawn rate was reduced to match the others.
The drops are already of low value compared to what they were. Before they become so abundant that their value decreases even further I just think it is time to reduce it.
For the idiots I will make it perfectly clear. I am suggesting the spawn rate is reduced to the same as all the other titans. I am not advocating it's removal.
