As far as I know, only money from MobHunting should stop dropping once the grind penalty has been reached. Yet, the XP and natural drops also no longer drops.

I know in a recent update you have made changes, tho my config seems to be fine.

Another thing, money still drops from spawners..

I have players complaining this is happening, what was the issue?

Just a configuration I missed.
