Starting up a thread for issues and errata in the Hiergamenon.
The following are issues noted in a fresh installation of 0.85 during the tutorial.
First, the Factions category has duplicate entries for all factions. Pariden actually has 3 entries and the third differs from the other two.

Next, there are two issues for Sovereigns:
1) The History for Karavox has a typo: "linneage" should be "lineage"
2) The History for Verga has confused text: "He stands as a full 10 feet high, ..." should be "He stands a full 10 feet high, ..."
Lastly the Game Concepts category has two, different entries titled "Introduction". The second one should probably be retitled "Tutorial Introduction" or similar.
Looks like I'm already a version behind. Time to go upgrade.
