Trenches and platforms do not correctly modify weapon firing range

[bannable]

My test setup was two pawns with chain shotguns, and I moved one pawn between a trench, soil and platform.

When a pawn was standing on a trench, the white circle indicator for the weapon range was reduced by 3 tiles. When a pawn was standing on a platform, the weapon range indicator was increased by 4 tiles.

In both cases, the actual firing range of the weapon -- by ordering a pawn to fire on other -- was not affected. This means that a pawn standing in a trench gets the huge cover bonus the trench provides without losing any weapon range, and on platforms a pawn loses cover without affecting their weapon range.
