Yes... I wonder if this is also prone to hallucination? A while (more than a year) ago I told Copilot to sort a list of integers. First, it gave me the code to sort it. I told it "no, sort the list yourself and give me the result". Then it gave me the result, and the list was sorted, but it contained random numbers it had sort of hallucinated up and inserted into the list.

How many numbers were in the list?
