You are right, but buildings are mapping like poligons, not like lines.
Piers could be mapped with lines, but in this case they should be in the middle of the pier, like a road, and not along the perimeter.
If they are mapped along the perimeter, then on the maps they are displayed as an empty square, not with area

Hi!
Thanks for your question! I did it because piers should be mapped like poligon, not like lines.
So, it has an area inside lines

Sorry, I can fix the obvious dragged node, but I cannot know if there is actually a ford, and can't fix edits I'm not sure about

Hi! Ok, thanks!
This news unsettled me a little, as I thought it meant polygons, not lines. But okay, I'll keep in mind for the future edits

Hello
Ok, sorry for it. Thanks for your message! I'll be more attentive.
