Problem summary
When bevelling a single polygon, the Vertex Normal map is not adhered to for the shift vector.
Customer reported version
modo.12.1v1
Customer reported platform
10.13
Steps to reproduce
1) Open the attached scene file. It contains a cube with a Vertex Normal map, and 2 vertices of the red polygon have had their normal direction altered. Ensure you've enabled Vertex Normal visibility under View > Show Vertex Normal.
2) Select only the red polygon.
3) Enable the Bevel tool (shortcut 'B').
4) In the Bevel tool properties, ensure "Use Vertex Normal Map" is enabled.
5) Activate the tool in the Viewport and drag the bevel upward using the blue tool handle. The polygon will bevel uniformly, but the 2 vertices that have altered normal directions should affect the shirt vector accordingly.
6) Revert the scene file (File > Revert) and select the red polygon and any adjacent polygon. Repeat steps 3 - 5, and you will see that the 2 vertices with altered normal directions are adhered to.

Reproduced by support
This bug has been reproduced in:
Windows 10
12.1v2
12.0v1
macOS 10.13
12.1v2
12.0v1
Earliest version tested
12.0v1 - The "Use Vertex Normal Map" Bevel tool feature did not exist before this version.
Expected behaviour
When "Use Vertex Normal Map" is enabled, bevelling a single polygon should result in the shift vector following the normal direction of each vertex of the polygon.
Actual behaviour
The shift vector of the Bevel tool ignores the normal direction as set by the Vertex Normal map.
