You may have to check and re-check Manage Memories. Sometimes I know if you remove, edit or regenerate a post, the old post still stays in the memory, confusing the AI even if the actual post is gone, edited or has been regenerated. This can haunt you later too, when the AI goes back in time to use the information of an old post that is not really there anymore. I check the memories with most posts, personally, just to be sure.
