I tried clicking on Mutual Friends and I get a 404 Not Found error. Why is this happening? I liked being able to see who I had in common with my friends :(

Confirmed and noted to the programmers.

I've discovered it's more than just mutual friends - when you click on UNs in trades or in the main sMail inbox you also get the same error

Where is it happening in trades? I'm not having trouble on the recent lots page myself.
