Ok thanks for the answer. Still one question. How is the priority of engery needed buildings? i hope defensive Systems have the highest priority.
To the one with the option of putting the industry priority to 0 if there is no production. i know that it produces credits and is intended, that's why this was a feature request. Because there are planets i only want the production to work to upgrade my mines or other important builings. But if the industry optimization works like you described, than this should be possible. i will do some further experiments.
