I relate. My characters have changed cities 3 times. The main family has changed employment. A secondary character became the second protagonist and also changed employment. I have a minor character still trying to break into protagonist status. My timeline was originally linear but is now flashing back and forth. At this point I've just thrown up my hands and said, "Okay, y'all, I'll iron out the ticky pieces best I can with prep. Y'all just discuss the rest amongst yourselves. When I start writing on November 1, just drag me along with you."
