Absolutely. It's why I hate editing. Two years ago while editing, this very story, I realized I had dropped a thread said a character was somewhere when she was actually somewhere else. In trying to fix those things... I rewrote twelve chapters completely and realized that I could no longer fit the rest of the novel with what I had written. By that time it was almost October and I decided I was just starting all over with the same characters and basic Idea. Here I am now and not a single version of this novel looks like the one before. Hopefully, I will eventually get a version I really like.
