I'm working on a base mesh and I've somehow created a ring of edges that are thicker than the other edges. When I try to transform any of the vertices along that thick ring of edges, it creates new faces, rather than transforming the positioning of the vertices.
Does anyone know what that is? Ideally, I'd like to know how I can make it like the other edges, as those vertices are not in a position I would like to keep.
