GPT deleted my thread in the chat

It seems like a minor problem but the thread that was deleted was the one I used the most, in fact it grew to 180 threads at one point since I used it in sequence but it deleted the root thread or the initial one which completely deleted that conversation. I would like to have photos but when I deleted it I can’t show anything, I don’t know why it happened if it was because I had a lot of threads and it just deleted the most important one from my entire history. Before deleting it I was having a problem in that specific thread and it was that the buttons weren’t appearing when gpt responds
