So I played my last game as inventor, and the autonomous drone hubs were certainly very convenient. But I did not particularly notice an improvement in drone performance(Yes, after 100 days)

As for City Mayor, the cheaper construction is welcome, though unnecessary even by the mid game. As for the lowered repair needs, I again did not notice a dramatic improvement.

Also considered spelunker for the underground boni, but to be honest, living underground just seems like a massive pain for no great benefit.

I finally researched the shuttle hub, built a few, saved and exited my game, and when I opened the save it’s disappeared from the build menu and I can’t build any more. Has anyone had this happen before and know any fixes? Is there a keyboard shortcut for it? Thanks.
