1. Create Path.
2. Attach a PROP to path (pick path).
3. Set up to move the Prop along the path as per normal.
4. At several points along path adjust the prop's path offset to create keys in "path offsets" in Timeline.
5. Now if you "Remove Object Animation" from prop, either while still attached to Path or Released from path,
the Offset keys remain in the timeline.
6. Also "Remove Object Animation" on the path, does not remove the Offsets keys in the Timeline.
