Multiple controllers on one spline breaks stuff

[_Aka_]

Hi,
Sorry I couldn't answer on Monday.
I was not able to reproduce the issue. I attached to this post a zip. It contains:

• your scene test.unity as a reference
  
• Scene 1 and Scene 2, which are modified versions of your scene
  
• a Cube prefab, used in Scene 1 and Scene 2
  

Your scene uses prefabs and scripts that are not included in your zip. So to be able to test, I made two scenes:

• Scene 1 is the same than test, except that I removed the gameobjects that are instances of a missing prefab, and replaced the needed ones of them with instances of the Cube prefab.
  
• Scene 2 is the same than Scene 1, expect that I removed all objects that are not either splines or controllers. This was to get ride of errors due to missing scripts
  

In both scenes I could not reproduce the issue.
What I suggest you is to:

1. Test with scene 2
   
2. If you could reproduce the bug, let me know.
   
3. If you could not, this means that the issue comes from one of the objects that are in your test scene but not in Scene 2. Gradually remove objects from test until you find the culprit.
   

That's it for now.
Happy new year
