Wither skeleton, endermen. and cows just to name a few are all displaying 100% drop chances for wither skulls. ender pearls. and leather respectively.

This affects many more mob drops as well. these are just three examples.

I am running version 0.6.6 fix 3 on forge 1.20.1 47.3.0

The "?" or other icons next to the items will show the drop percentage modifier. That is it's chance to drop in the pool (100% because it's the only item there). I know that's a bit confusing, so I am plotting and scheming on a bit of a rework
