Some units, such as scouts, minutemen, or units upgraded from them, get the "ignores terrain cost" promotion which means every terrain tile costs 1 movement point (or less if it's a road). However, the woodsman promotion explicitly says that forests and jungles cost half the movement points.
My question is, how many movements points does a forest tile cost for a unit with both of these promotions? 1.0 or 0.5?
