I have an add-in that has been used successfully for more than a year now and recently started seeing an error within on of my functions when attempting to get the reference plane for a sketch. Below is the error, which indicates that I need to roll back before the sketch is created to get the sketch plane. Is this an intended change and if so is it documented anywhere?
File "C:\Users/ALDEN/fusion-add-in\commands\modeling\generate_laser_features.py", line 1038, in get_centerpoints
sketch_plane = centerpoint_sketch.referencePlane # Get plane sketch was created on to add another sketch to later
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

return _fusion.Sketch__get_referencePlane(self)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^^^^^^
RuntimeError: 3 : referencePlane is a BRefFace - need to roll timeline back before sketch
