* On the "Invasion" map: Lairs don't generate a "boss" when you destroy them, but the text displayed at the top of the screen when you mouse over the lairs says they do.
* When playing as knights, and you select a builder and mouse over the knight stables, it says you need a level 2 keep to build it. In fact you need a level 3 keep.
* When playing as knights, there are double damage ("paladin") and triple damage upgrades for knights. The triple damage one says it's "vs undead", but there is no such qualifier for the double damage upgrade.
