I don't know about Vicki-specific problems, but this sounds like a case of the yRotate angle wrapping between positive and negative. If the yRotate goes from -1 to +359, or, say, -350 to +4, the change is really very small but can be interpreted by the animation arithmetic as a full-circle pirouette. Since you can't get into the Walk Designer to fix their math, you might try re-orienting the path so that it doesn't cross either 180 or 0. Or, if the direction of her walk with respect to fixed props is critical, you might create a secondary "ground" or platform, that is turned 90 degrees from the real ground, and parent your furniture to this platform instead of to the real ground.
