If hexagon hitboxes are going to be a big thing (like for tree's, bushes, stockpiles) there probably not going to play nice with a minimal rotation angel of 11.25 degree. (user build/placement wise)
But than again, the only nice hexagon seems to be a regular one. (with some 60 degree related angle snapping)
That makes me wonder ... if that 90/8 snap angle is now not a real game thing anymore, but just a leftover client thing. (game spawned tree's seems to suggest the latter)
