I'm a little surprised no one has mentioned this, but I couldn't find it in the list of problems found.  Before you say that this has already be found months ago, those were the skins for Rook's towers.  The problem I've found is this:  when playing as Rook on the dark side, there are two problems: 1. When you mouse over the button for Rook's "Power of the Tower" ability, it says he raises a Tower of Light.  When I do raise one up, it looks like a Tower of Darkness, but when you mouse over it, the description says Tower of Light.

Dunno if this should be labelled as a bug or a UI error, but there's the problem.
