I just entered Destard, Deceit and then Despise with one of my elves, wearing nothing that added night sight. The dungeons seemed illuminated, so I don't know if it's something about the patch, or what's an existing bug. Crossing certain boundaries (not server lines) tends to render elves' sight no better than humans'. Why, I don't know, but my elves carry Nocturne Earrings for this reason.
