Broken: Blender 2.74
Worked: Blender 2.72
Short description of error
In a model with multiple isolated polygons, users often want to join verts within these polygons using the Vertex Connect tool. However, this no longer works.
Here we have multiple polygons:
In Blender 2.74, pressing the J-key results in this:
A single line is drawn across the entire model, not within each isolated polygon.
In Blender 2,72, pressing the J-ket resulted in this:
...which is almost always what you'd want.
Exact steps for others to reproduce the error
Take this file with a couple of isolated N-gons:
Press the J key.
Watch it try and make one continuous connection insteaad of connecting up each set of verts as it would in Blender 2.72.
