The box and the instruction manual both say that the game includes 8 Chaos Warband figures. I got 16 (four from each Ruinous Power). Is this a typo or did I get too many figures? What initially drew my attention was that I ran out of 1 power black bases fairly quickly. Anyone else run into this?

You are probably mistaking Chaos Cultists for Chaos Warbands. You can tell the difference by noting that Warbands have pointy shoulders while Cultists do not. There should be a total of 8 Cultists and 8 Warbands. Also, you should know that Cultists are Rank 1 units while Warbands are Rank 2 units. You should have 8 Rank 1 bases and 4 Rank 2 bases left over for the purpose of corrupting Imperial units.

You are exactly right. The difference in the figures is so small I completely overlooked it. Thanks.
