Look, the button to not notify people you did an edit is *right there*. It's a lot of effort sometimes to not change the text of one of my more popular chapters to some Vogon poetry or something
I did this once. A character was briefly mentioned in an early chapter. Some time later, I started writing down information for every character in the story, and made a slight error with her name. Then, the character became more important, and I kept using the slightly wrong name. When I noticed my mistake, I just changed the initial mention instead of confusing up-to-date readers.
I want to write sexy stuff but am too busy contemplating the psychological effect the proof of god's existence would have on my characters.
Um. Their god is kind of you. You could just invoke divine intervention, at that point. I honestly don't think anybody would blame you.
Nice to see that you got out of the rut almost immediately, rather than the gruelling long process of recovery.
