In the core rules, it states that the Total War game mode allows you and your oppenent to each take 1-3 huge based models for free. I'm a bit confused by this as I was recently told by someone that the game mode doesn't allow that anymore and instead just requires a colossal or gargantuan be in the list. This is also how the list builder seems to function as well since it gives an error saying just that and there is no option to mark a model as being free for the game mode.
Was this a change that was made and not reflected in the core rules or is this just a limitation of the list builder?
