Switching between unconnected splines

[smaras]

Hi,
From my understanding, you use SwitchTo to instantly change the controller's spline upon landing. Based on that understanding, you don't need to call SwitchTo to do that, and should instead to just change the value of the controller's Spline property. The method SwitchTo is there so you can do a gradual transition between two splines, which is not your case.
Let me know if my answer is not helpful, and have a nice day.

Thanks for the quick response. I did like you said and now the error is gone.  

Thanks
