Curvy Connections Need Help

[aberent]

I am trying to use Curvy Connections for track switching in a Train Game, However it seems buggy.  First when my connections join an existing track all my Spline Walkers (Train + Cars) immediately jump onto the destination spline, instead of walking on 1 by 1.

Also when I back up on to the Parent Spline I get a StackOverflow error:

It just keeps going,
