I have big troubles understanding how the previous/next-navigation can work as I want it to. Site’s adress is: http://norsted.com/
For example, on the default landing page (Work) I have the masonry thumbnails for the projects I want to show. When you then open up a project detail page (a post actually, set with the hidden category “Work”) and then click on “next”, it goes to the next project but then it jumps to another post (that has a category name set to “Illustration”. I do not want this to happen, but only to rotate between the posts in the same category.
