Problem Comments Seem to Refer to Wrong Problem

[tmr]

I noticed several times today comments on a problem that didn't seem to pertain to that problem.  Since it was on more than one, I'm wondering if the problem/comment links have been corrupted in some way.  Problem 13771 is an example where the comments seem to refer to some other problem.

Hi Tmr,

I think this is human error. This is unfortunately fairly common when the position is from black's point of view.  These mistakes should be less common now that the board co-ordinates are on by default.  I believe Qf7 should be read as Qf2. Usually it is fairly easy to see where the commenter has made a mistake but what makes it more confusing is the Nf7, but I think this one is a typo and refers to Bf7 (or correctly Bf2).  The user that responds, "Both Qf7 and Nf7 look like very difficult moves indeed. I'm usually pretty critical, but this problem is ok.", is probably being sarcastic and is reading the board correctly.

Regards,
Richard.

Thanks, that makes sense.
