Comment 31 for bug 1234725

ad a): not in my copy of the branch! As you see in the first attached picture, there are many anchors beside the main Port Spot location; in minor blue houses and even without buildhelp support. Please have a look into it, that's not good as is!

b) and c) are somewhat inter-related. My thought on Anchors is, that if there is no grave argument against them, they should pose a *reliable* source of information about the existence of the Port Spot. Under this measure the blue "radius houses" can be dropped because their only sense of existence was to warn about an invisible Port Spot. When the PS is always visible - unless you build on it - then you can drop the radius houses and reduce the blue indicators to the core PS (where they make great sense). The blue radius houses are graphical noise and - in contrast to the anchor - non-intuitive; if feasible they should be dropped. The reliability of the Anchor as a PS indicator is not guaranteed if random actions like forester and farmer may remove it from sight of the player without his awareness. Shorelines with PS are probably nonsense because they would render shorelines of anchors; probably editors would remove the multitude!
