Hi Xorimuth,
I just wanted to report a kind-of issue, not sure if it is by design or fixable at all, but in my opintion it should be considered a bug.
When you are connecting an energy producing power network via transformer to another one, and then connecting the second to the first either directly or through a second transformer, any power pole limits just get hit instantly - and all the power poles explode. My guess is that some kind of feedback loop is created that starts drawing virtually an infinite amount of power when there is no "end" to a consuming power network.
Let me know if you need any more details.
Kind regards,
