Spline resets after an error is thrown about an incorrect target

If a user connects a spline to a "Get World Location at Distance Along Spline" and then uses that Vector in an event. The spline will be reset if the user then disconnects the spline variable from the "Get World Location at Distance Along Spline" and compiles.

1. Open the Editor
2. Create a New Actor Blueprint
3. Add a spline component to the blueprint
4. Create the blueprint in image (Step one)
5. Add the Actor to the level
6. Add segments to the spline (image for reference (step two))
7. Add a vector and create the blueprint in the attached image (Step three)
8. Disconnect the spline variable from the "Get world Location at Distance Along Spline" node
9. Compile, ignore error
10. Add another Variable to the blueprint
11. Compile
12. Notice that the spline has been reset in the editor

Expected: The Spline would hold it's shape
Result: The spline reverts back to it's default shape
