Here's a topic i've never really understood. Namely, the effect of power stalling on construction.
Eg I am building a T3 PGen (or any other building) and i don't have enough energy in storage to build it completely. As i start construction I realise I need it urgently and assign every single engineer I own to assist construction.
Once they are all assisting, I can see my energy bar is showing - 500. Will having this -500 deficit cause the building to complete slower than if i removed some of the engineers (so for eg the deficit was -100) or if I removed enough engineers so that the energy bar was showing a slight positive.
Hope that makes sense!
