They used to work, they dont now

Something changed between mekanism 9.2.1-291 and 295 and Actually Additions r75 and r88 to break it

I guess it won't take any power anymore. I personally don't use Actually Additions, but looking at there changelog (and associated commits), they've dropped support for RF energy and fully support Forge Energy (and a couple others).
Mekanism doesn't support Forge Energy at this moment.

Still takes power from the phantom energyfaces, its just the standard ones that deposit items into the machines that dont work
