The software Gods and the global cache

How many times have you done this: Scrolled through the code, saw something totally bogus, fixed it, and then got a bug report from someone just discovering the bug you fixed. This has happened too many times to be mere coincidence and it's not just bug reports. Discuss how you might implement a feature, and someone will request it right out of the blue.

I believe there are software Gods who maintain a global cache of all project activity. When you think of something or touch the code, the cache gets updated and someone gets notified.
