I don't have a clue if the unprofitable thing is on or off, so its useless, and I understand that I have an incentive to supply more to the city to descrease the cost of engineers but with the cost of resources always going up I can't provide enough energy to get the 4 engineer, it cost 1.6e7 now and I barely have 1e6 money after 1 hour waiting, and the fact that I need to keep selling the energy manually because the cost of batteries and max capacity is low makes impossible to leave the game alone for 10 minutes or my money goes to zero because the autosell is the worst.
And now the cost of the engineer is 1.9e7 again because the costs keeps rising and I need to keep proving less energy for the city. And my money now is only 100k even tough I didn't buy anything.
So now I will stop proving the city and focus only on the research and see if I can get past this part.
