Seeing as Consimworld is down I thought I would ask here and see if anyone is reading. Rule 19.3b and 19.3f seem to contradict each other regarding hexsides.
19.3b says "These hexes add if any part of the hex (including all that hex's hexsides) is crossed."
19.3f says "Hexsides allow LOS if the unit could see through at least one of the hexes adjacent to the hexside."
So one rule says it affects LOS, the other says it doesn't if only one hex has the obstacle?
