Mod Version: 1.2.0
Mod Loader: fabric

Description:
Original mobs and the Warden don’t drop any of the loot

To Reproduce:
Kill Warden, heart should drop 100% of the time but doesn’t. Enter the Otherside, mobs don’t drop any loot upon death.

I killed the warden and it seems to be dropping everything, so I think another mod/datapack is replacing its loot table. Deeper and Darker mobs not dropping anything has been fixed in 1.2.1
