I have what I perceive to be an error, Spoiler : Fieldsman I & II give 15% Hills defense (I) and 15% Hills attack (II), but Fieldsman III, TAKES AWAY 20% of both attributes, but GIVES 20% to everything else. Its an overall -5% on Hills, with Fieldsman III, Should I take this promotion literally, and lose the hills, or is this a mistake in promotions.??? Promotions should ADD to a units attributes, not remove them. So I believe it should be changed to +20% hills attack and defense. Nb: I've only promoted to Woodsmand I & II, Combat II, III, IV and Guerrilla II, all others were field promotions. 2nd Bug, Underlying terrain is used in bonus calculations. Spoiler : ] here the base terrain of a desert is used to calculate the terrain bonuses. I had a unit with Guerrilla III, yet it was penalised due to the terrain. The other mountains didn't have a health penalty. This also goes for Great General units, who have Fury III, who are penalised by the underlying terrain.
