I don't know the proper term... but I believe in the past when a player went out mining with the staff of power it would collect the dropped items in a small black orb. This was great for reducing the impact on both the server and the client by restricting it to a single entity in the world rather than 2197 (13x13x13). What is odd is that I recall seeing black orbs appearing every now and then with the items dropped being within them, is this from the same mod though?

Not sure if this hasn't been re-added or if it just has some issues working full-time.

Was fixed in new update
