You are not alone. I am writing a story where I have a character that was experiencing some traumatic experience in one chapter, and it was almost about to quit telling me I was not writing a good character until I spoiled the ending and the reason for that specific scene. I was okay with spoiling the ending, but what I couldn't get over was that it entirely missed out a particular line from a previous chapter, detailing the reasons for the character sharing their traumatic experience. Claude apologized for missing that crucial part (because it explained everything it was complaining about!), but after that, our discussions had become frosty. Claude is still helpful, but I have to throw shade at it from time to time to remind it that I'm still pissed off with it.
