I don't leave certain machines hooked up to my power grid (Immersive Engineering Water Wheels), because in the past they were known to stay running (i.e. draining power) even when they weren't doing anything. Specifically, the Thermionic Fabricator and the Railcraft Rock Crusher.
In Skyblock, when I disconnect the power from the Rock Crusher, the MV Immersive Wire just disappears. I disconnect by simply pickaxe'ing the Connector, and usually the MV Wire drops onto the floor and I can pick it up. But in this modpack, I only get the Connector back, and it happens every time I do this with the Rock Crusher (and only the Rock Crusher). So where is the MV Wire item going? Is it glitching thru the floor and falling into the void? Is it being eaten by the Rock Crusher, is that black area on the top of the machine actually an opening that can eat the wire? LOL Why does this only happen with this specific machine? Very aggravating since gold is in short supply during early game and thus, so is electrum.
