Chat GPT is deleting my Israel conflict research chats.

So I've been generating informative content and using chat GPT to do research on Israeli history, Zionism and the conflict. A few of my chats that have been automatically flagged as controversial, have been deleted. Please back up anything you have. They are gone and even chat GPT has no memory of them even when I give them the documentation.

Edit: I have made a custom GPT that is only allowed to access research sites. So it's not the regular GPT. I also have the paid version which is much more accurate.
