You say this like it's a bad thing...
It's good to shake the engies out of their ruts from time to time, intentionally or not.
It IS a bad thing. If Muse wanted intentionally to make game more difficult for engineers - they would do so (for instance chem nerf). But I think this is mostly unintentional and bad for the game, because many times I know I hit the component, the game gives me correct sound and yet there is no effect. Before 1.7 there wasn't such a problem and I could easily hit and fix everything running. Now I can't and I will consider this as a bug, a thing to be fixed.
