The title says it all, EVERY SINGLE MOB DOESN'T HAVE LOOT DROP WHEN KILLED!!!! Even the Caves and Cliffs ones!!!! On both game modes too.

Steps to reproduce:
1. Spawn any mob or find one
2. Kill the mob and notice how they don't drop loot they just drop xp

Expected results:
The mob should drop their respective loot

Actual results:
The mob dies and their loot doesn't show
