There is a very annoying bug that is screwing up archives. Not all proper weeks/months are showing up in the archive index. Sometimes, it will reset properly if you turn archiving totally off and then back on. Sometimes it won't. Trying to figure out how to fix this quickly (I didn't right the current code on this one, so it's a bit of a challenge to dig into) without writing too much code I'll soon need to throw away because I'm planning on redoing how archives work in general soon (but that's a pretty big project). Archiving has always been too confusing in Blogger. Could be much simpler.
