Circuits that use power transformers keep overloading when the game thinks there are less power generators that can theoretically provide all the power in the same circuit.
I think it's because the game doesn't really flag power transformers as a power generator in the local circuit.
Steps to Reproduce
Steps to reproduce: 1. Build circuit that uses power and is connected to a transformer that provides it power. Circuit will keep overloading when it is in use. 2. Add enough generators [i.e. 3 Manual Generators; Priority 1] in local circuit such that it theoretically exceeds total power demand to stop circuit overload problem.
