Increase Drops stops working middle of Act 2

[lagosliph]

I am using increased drop rate (preset of "I want to find Tryael's today!") and it is working correctly through Act 1 and Half of Act 2. However, around entering Lost City, all equipment ceases to drop. The only drops from enemies are potions, keys, gems, and occasional runes. I turned off all mod settings to test, and it seems to carry over where anywhere past that part of Act 2, nothing equipment/charm wise will drop. I can return to Act 1 and everything returns to normal without issue. Even if i use the Tyrael's Preset, they drop lots of loot to pick up. However, I did notice that Andariel also doesn't drop any items, just 1 gem and nothing else. Not sure what is going on.
