The patch 3.3 Sub-Menu background images are out of order. The Icecrown 5-Man image should be insert between Quests and Miscellaneous. Don't ask me how I noticed this, all I know is that it's wrong, and that it's bugging me.
Whoa! Yes, you are right, I never noticed that, I also checked the source of the page and it says something like
<div class="first">
<div class="second">
<div class="fifth">
<div class="third">... etc..
I know you asked us not to ask you.. But how did you notice this!?
