I've got a Charging Bench setup, but it has no power coming through it whatsoever. It's ~3-4 blocks away from a BatBox, and as I said, is not connected at all to any powersource, as far as I know. Yet for some reason it will start to drain power from the BatBox. This happened with both LV and MV charging tables. The table has no items in it whatsoever, and if I move it a block or two away, then it stops charging.
There was no crash, no errors, so sadly no log to help.
EDIT: Note that as soon as I connect the BatBox to the Charging Bench, then disconnect shortly after, it keeps on charging still.
