No, [[Warhammer 40k - Lexicanum:Editors|normal Editors]] do not have access to the ''deletion'' tools. What you most probably witnessed was a process called ''Page blanking'' in which the content was "overwritten" with a different (possibly even "empty" content). This can sometimes be a legitimate process, for example when [[Warhammer 40k - Lexicanum:Citation|unsourced]] content is removed in preparation of overhauling/ re-creating an article. Or because content was moved from one article to a more appropriate article. Unfortunately sometimes Editors do intentionally and with no legitimate reason [[Warhammer 40k - Lexicanum:Vandalism|vandalize]] articles by "blanking" them completely or partly. If you come across such acts, please immediately report them to an [[Warhammer 40k - Lexicanum:Administrators|AdministratorsAdministrator]] who will take corresponding measures.
