SUMMARY the snap to assistants option misbehaves when moving back and forth from Freehand Brush Tool and Multibrush Tool using the keyboard shortcut. STEPS TO REPRODUCE 1. Select Freehand Brush Tool with keyboard shortcut 'b' 2. Toggle Snap to assistants with keyboard shortcut 's' 3. Draw: snaps OK 4. Select Multibrush Tool with keyboard shortcut 'q' 5. Draw OBSERVED RESULT It behaves like if the Snap to assistants checkbox were selected although it’s not. The checkbox must be selected. If the box is checked manually instead of using the keyboard shortcut, it seems to work OK. EXPECTED RESULT Snapping to assistant should be consistent between tools, no matter how they are toggled.
