Yes sure, here it is. If you click on the right power pole you can see that the consumption of the assembler is 44.7 kW and not 48.9 kw as it should be (41.9 kW + 7 kW Drain)

Exactly, quite a small issue but maybe there are some other systems influenced by this.

The power drain is the value of the input power of the machine when not active. The value as well as the actual measure on the network show 7kW on the tier 3 assembler, independent of any efficiency modules. I have no idea what you mean by: "The drain power is reduced ONLY when the machine is ...

Minor Bug: Up to a energy consumption reduction of 50% the drain stays at the normal value and isn't influenced by modules/beacons. From 55% to 80% the Drain Power reduces from the default 100% Value (e.g 7 kW for the Assembler 3) to ~40% (~2.4 kW for the Assembler 3 for -80%) The values in between ...
