During a game a couple days ago, I was measuring a firing arc with Luke Skywalker. It was pretty darn hard to call. So I got down real close and and tried to eyeball it better and I just barely missed by a millimeter, or less. However, I noticed that Luke's printed firing arc is smaller than what it is supposed to be! It looks like a misprint to me, see pictures below.
I was going to just measure the firing arc from the edge of the corner like it is supposed to be. However it looks like the inside end of the arc is in the wrong spot too. The inside end of the arc is closer to the center of the model than it should be. If I used that inside end point and the corner of the template point to base my line from, then I would have too wide of a firing arc. As it stands I have too narrow of a firing arc. In the above mentioned game, I am very confident I would have hit if the arc would have been correct.
I went through my models and found 4 more that have a similar misprint! My questions are:
1. Is this common?
2. How to deal with this in future games?
Thanks
