Sound Effect for "Your inventory is full."

This would help provide some audio feedback when trying to pick up an item I can’t due to a full inventory, something I’ve admittedly often done more than a few times in a row before realizing it. Additionally, if other players can hear the sound, it better communicates to them you want an item but can’t hold it.

Perhaps a sound for attempting pick up a “protected” drop credited to another player could be added as well?
