Dreamwidth style system discussion

Extremely weird behavior when I check Use layout's stylesheet(s): sidebar is pushed down, the last entry on the page overlaps second to last, .entry-interaction-links have lost some of their background, .page-read .poster, .page-network .poster have jumped to the upper left corner of the window, and while the padding and margin for .module ul, .module ul li worked, for some reason there's still a disc even though it shouldn't be there (it's only supposed to appear in .contents ul li). Some of this is still true even if I uncheck Use layout's stylesheet(s).

I'm going through the css to see if I deleted a curly bracket or a quote or added something that doesn't belong, but I'm not seeing anything at the moment. A fresh set of eyes to point out what I've missed would be very much appreciated!
