- Powercells/Batteries now distribute power when Powergen for network is 0 - Powercells/Batteries will only distribute power to "Active" machines lowering network drain - All machines/Powercells-Batteries act as power pass through ie no longer a network end point - note this only happened on reload of game they worked like this when laid out this way just game save/reload caused machines/Powercells to act as end point. - fixed Issue max_stack to stack_max, https://gitlab.icynet.eu/evert/elepower/-/issues/5
