No kidding! My assumptions were all wrong. Their teams went nuts on this one.
Logged in to discover my that my recently completed base (started over last week on the PS4) now has to be powered, and the power system is way more complex than I’d expected. I’m out of my depth, to be honest, but in a good way.
Edit: If anyone figures out how to unlock power switches, which I don’t see in the tech tree, let me know. Assuming I have to go blueprint hunting for them.
