One of those 'let me know if you notice anything broken' things is that posts with special characters -- this includes the extended vowels often used in Alemannia, also Word replacements like smartquotes, mdashes, and elipses -- will not display properly. The content is still in the post (if you hit 'modify' it will bring it all up) but the display template chokes.
DO NOT FREAK OUT, the post is still there, I promise, and even if it were not, this is why I take database backups.
SO, IF YOU SEE ANY OF THESE BLANKED POSTS and you can't edit them yourself, please link the threads here and I will get them all fixed mas rápidamente. <3
