On February 3, I attempted the minor upgrade from Movable Type Enterprise 4.32 to version 4.33. This upgrade promised a few bug fixes and security patches. Unfortunately, later that day I discovered a bug with the publishing of date-based archives. I confirmed this bug on forums.movabletype.org.
Six Apart has released a patch to 4.33 that must be manually applied. We will instead wait for the official 4.34 release.
