I have a very similar situation. Except it isn't even a ticket, just an export of a very long "conversation" with ChatGPT with a vague indication that this is what needs to be implemented. When questioned about it, the person insists they completely understood it before but just forgot after a few days. Sometimes the prompts are removed. Lots of contradictory material in it, some doesn't make sense even in context. Very difficult to figure out what is wanted.
