Issue description:

In another 1.15 pack, I was never able to get a energy cube into the energy slot of the digiminer so I assumed it was something still being worked on.
In this pack, right from the start I was able to put an ultimate energy cube into digiminer as well as take it out and charge it and put it back again, at least a few times.

I just charged it again and this time however, it just won't go in the slot. I'm wondering if it picked up some metadata or something causing this to happen?

for reference, here's the metadata for the cube

A 'bug' exists currently that doesn't allow insertion of energy cubes when a machine's energy buffer is full. This is fixed in v10.
