Creating a Gordon surface, it can happen that when a sketch of it is modified, the Freehand_Bsplines that have end points close to each other get snapped into one point, resulting in faulting recalculation of the Gordon. Can't be rescued easily as well. That behaviour wasn't noticed in 0.21.2.
In the example file, open Sketch001 and move the right end point slightly upwards, that triggers the behaviour.
