Sometimes the highest version of the nightingale blade (highest/best version is obtained at level 46) wont show up at a grind stone to be upgraded, and as far as i'm aware, there is no fix. This seems to happen to a majority of players, though not consistent. In other words, some people are able to upgrade the lvl 46 version, most, however, cannot, and sometimes it may show up at a grindstone. Kind of annoying
