This error means you have two Biped IK Script's on your characters.

In your meeting that presents this error

  • Check each character. Which part of the charact to check

  • and make sure they only have one Biped IK (Script) How to identify and remove the culprit script

Remove the second Biped IK (Script) if it exists
