Line renderer is broken when using loop or edge vertexes.
First image shows the line renderer connecting to another line renderer in the scene, it’s not supposed to there is no point for it in the list. When moved around it still links to the other line renderer and updates the mesh to follow it.
Also there are no corner verts on the inside of the shape? not sure if that is intended.
When using loop with >0 edge verts it randomly links to another line renderer.
When using loop and 0 corner verts it does not connect properly.
Points as a ploygon collider for reference:
