Both fixed. Some info if you're curious! The first one was 'cuz we have a strange bug with SMW sometimes, where random pages lose their properties (the Neathproofed quality page in this case). It's easily fixed by purging but can cause a ruckus if it's something that other pages use (where they also get cached the wrong way). The second, pages and links need time to update again once something they use is changed. It's automatic but can take a while, especially for categories. I started a process to force-refresh all the links a while back, should be good in a bit (still takes like half a day with all the pages we have).
