1.BONUS: when a settler is scored that is standing on the same column with one (or two) surveyor(s), the player
scoring the settler gets a +4 points for each surveyor! (note: an surveyor is moved after the settler is scored!)
2.REMOVING fallen-behind settlers: whenever the eastern-most surveyor is moved from a column with one (or
more) standing settlers (not trappers - they remain lying down until the end of the game), remove these settler(s)
and all settlers “east” of this column from the tiles and return them to their owners. A player may place a settler
on a just-placed tile in colums “east” of the surveyors, but it is dangerous as such a settler (not a trapper) will be
removed immediately after the next scoring!
