I'm not sure this is exactly a bug, or whether this is the best place to report this, but I thought you (the developers) might want to know about it and wasn't sure where else to put it:
My friend is using Forever on her WordPress.com blog ((mostly) sewn) and she was having a problem with the latest posts—instead of 4 posts in 4 columns, she had three posts and an empty column, the fourth-latest post was simply not shown. The main post area below began with the fifth-latest post. It turned out the blog was set to display only 3 posts per page, but Forever was still extracting 4 posts to display but only displaying 3 of them.
I figured the theme might not have been tested with such a low posts-per-page setting. I'm not sure it's exactly a bug since it is kind of honouring the blog-wide posts-per-page setting, but it's definitely a weird problem that someone with less experience with WordPress/blogs wouldn't know how to solve.
Maybe in a future version you could override the posts-per-page setting for the latest posts section, or at least put a note in the theme info warning people to set their posts-per-page to 4 posts minimum!
Great theme by the way!
