Subd bug with MoveUVN

When I move points with MuveUVN, the subd seems to be transformed in preview, yet when I release the slider, it will jump back to its original state. (latest v7 wip)

Apologies for the delayed reply. Thanks for the report, this is filed as an internal report, RH-49848 for future reference. Hopefully we can add this type of editing support soon. Thanks again!
