I just purchased AB3 and noticed a few bugs while trying to input an Ork Blood Axe army.
Under the Kommando listing for Blood Axes, it only has them as Elite choices. They are both Elite and Troop choices.
Also, under the Looted vehicle options, if you select a looted Land Raider, it doesn't give the options for any ork upgrades (like Red Paint Job or Grot Riggers) but the option is available on the Basalisk and Russ Demolisher vehicles.
