Browsing through the histfig list, using the filter options, necromancers and werebeasts are properly listed, but vampires don't show up. Checking the pages for deities show them cursing people with vampirism and werebeast-ness in about equal amounts; and the histfig that gets cursed shows the deity as their "Lineage Curse Parent", it's just that Legends Viewer isn't listing them as a vampire.
