I just started a new project today with 4.0.4.1 and noticed that every icon class I use for a document type that comes after Developer Registry Item is off by one icon. I took a look at /umbraco/images/umbraco/sprites.png and noticed that there is no icon in it for Developer Xslt and that is causing treeIcons.css to throw everything off by one icon.

Before I go hacking away, I want to know if anyone else is having this problem? Am I missing something?
