So I have a basic setup of Coal Generator and a Pulverizer next to it and the energy gets transferred to the Pulverizer then it resets to 0. Using 1.2.1 version of the mod.

If you connect it up with a cable it doesn't reset to 0, but it simply doesn't work :) Energy level stays put and nothing gets pulverised.

@ChristopherMeek yeah, in the latest version, this is happening to me too
