This is driving me crazy! Why does neither Kaedweni Cavalry nor Thaler remove the charge from Kaedweni Revenant? One could argue that for some reason it wouldn't be counted as a charge, but that would be immediately proved wrong by Falibor, who destroys Kaedweni Revenants just fine. You can't use an order without a charge, and the icon ("x1") clearly says that Kaedweni Revenant has a charge.
