I can't build past these red lines. But from what I can tell, if I build vertically, I can go really far. Why is that? The plot size seems to be equal in all directions, so what gives? Feel like it has to be something obvious that I'm just not aware of.

EDIT: Thanks to u/SiliconStew, figured out that box with red lines is in fact my pier not allowing any modules in that area. As he said, "L/LX docking areas extend to infinity outside the plot area". So basically I need to build AWAY from the pier.
