About an hour ago, an answer was posted to this question by a 1-rep user. It wasn't the best answer, but to me it clearly was an attempt at answering the question. While it referenced the existing answer, it only did so to say "that answer is wrong" before launching into an answer of its own.
Nonetheless, it's now been converted into a comment on that answer. What's more, since it was too long to fit inside a single comment, it now cuts off awkwardly halfway through:
I have no idea why this was done. Regardless of its quality as an answer, it was clearly intended to be an answer, not a comment. If anything, it should have been deleted altogether (I'll note that the same user's first attempt at answering that question was deleted within 20 minutes of being posted).
Why was this answer converted into a comment?
