/* 	Edit this file to customise the Uncyclopedia (vector) skin for the entire site. Anything that is not skin-specific can go in MediaWiki:Common.css. This is at the top of the css file you linked, defining the skin as vector in all but name. It's vector with some styling tweaks, no different to the theme w:c:monobook makes for wikis. Nothing out of the ordinary.

And yes, monobook is full of bugs. They aren't given as much priority as oasis bugs which is a bit of a shame but I guess you have to draw the line somewhere.
