Broken: Blender 2.71 "stable"
Worked: i don't remember a version of Blender in which the Bmesh knife was working without problems
Short description of error
Knife can duplicate vertices on cut edges, as reported here :
Exact steps for others to reproduce the error
- Load the blend with Load UI so you get the same view and visual
- press K and try to cut at these locations :
- If you managed to did the cut roughly there, you'll notice the vertices there are doubled :
The oddity is that it does not happen everytime, but it happens.
