Finally figured out why my machines take random damage on 2.0

Since I started my first game on 2.0 (what's up community mappers), I noticed my stuff occasionally taking tiny bits of damage here and there. Super, super minimal, but puzzling.

What's going on? Did they add some new environmental hazard on Nauvis? A harsh wind? Termites? Something to encourage us to properly set up our Roboports with repair packs before blasting off? Do machines "decay" while not in use??

I'd read about all the major features and a lot of the minor ones, but didn't remember anything like this. All my reddit searches turned up nothing, and I didn't really feel like combing through the patch notes.

Ah well. I learned to live with it and went on with my engineering. I've finally gotten to bots, and they went to work fixing all the dings and dents in my equipment. But just now, I was setting up yellow science when, suddenly, it clicked.

You see, dear reader, there were some hotkey changes with the patch. The devs took "Pause Game"—a feature I (ab)use frequently when I need a little time to think—off of Shift+Spacebar. A change that I had quickly reversed when I started Space Age.

But, what I didn't realize, is that Shift+Spacebar hadn't disappeared from the controls. Nope. It had moved to another action. And rebinding it didn't remove it from its new home.

And what was that new home, you might ask? Shoot Selected, baby.

So. That's the story of how I realized 🙆🏻‍♀️ I am the one 🙆🏻‍♀️ who's been doing all that "random" chip damage to my factory.

¯\_(ツ)_/¯
