- SMESs will now try to balance their inputs and outputs. This will correct the situations where some SMESs charge at full rate, starving other SMESs who are trying to charge from the same power net. In terms of output, multiple SMESs (such as, solar SMESs) will try to provide equal amount of power to the powernet. - SMESs processing is now slightly different. UI now displays a "Disconnected or No Charge" error when the SMES does not have cable connection to output to, or when stored charge is zero. Once this problem is resolved (either by charging the SMES or by connecting it via wires) it will automatically begin outputting again. - The only tiny bug i have registered so far is related to number precision. It is possible that powernets may gain or lose few watts (talking about 1-5 watts per powernet at most, it is negligible)
