How often have I noticed some "odd behavior" in testing, and later wasn't able to reproduce it? Some nagging feeling that I broke something remained, but since I've deployed a new version (that fixed something else), and I couldn't reproduce the "odd behavior", I tricked myself into ignoring it. And then I deployed to production, and shit hit the fan. Now I try to pay more attention to those small, nagging feelings of doubt, but it takes conscious effort.
