- add a cube or use the default cube if you have one.
- convert the top face of the cube to triangles (ctrl t)
- move the top four vertices (the ones containing the triangles) to varying heights.
- Select the 3 vertices of one of the triangles and do a cursor to selection (Shift s)
- The cursor isn’t where its supposed to be (at the center of the 3 vertices) !!
Could some other people confirm that this happens for them. If so, I will file a bug report.
