Assistant overwritting another one on the open ai dashboard

Yesterday, I was working on Assistant X, and out of nowhere, it got completely overwritten by Assistant Y that was on the same project. Even the prompt and function I had set up got replaced without any warning. It messed up my workflow.

Has this ever happened to you? How did you deal with it?

Happened to me today. Lost a lot of work. Opened a ticket, hope they can recover the lost data.

Did you ever get is back?
