When I type "Reformation" in Factbook, it suggests (among others) the topic "Reformation Era (1517 – 1699)". When I select this topic, the Factbook returns no information.
I recognize that this is a Timeline era and there might be better topics that contain what I am looking for. But I don't believe that Factbook should suggest a topic that returns nothing. At the least Factbook should have a "see also" entry, perhaps to a list of more suitable topics.

Also, this useless topic appears twice in the pick list of topics in the Factbook.
