Reminds me of an incident in 2015 where a colleague and I stayed late trying to figure out a strange case of our physics engine producing NaN values out of nowhere. Even when we found the culprit it took us so long to believe our findings. There was a bug in Visual Studio's intrinsics for certain geometric functions (I believe it was sin). There was even a bug report for it with a reply saying they were aware of the issue and had no immediate plan to fix it.
