Helloo! im a student trying out a ribbon rig for the first time and i encountered this problem.

The FKIK Switch works. The ribbon rig's sine blend does not work. Well, the attributes function properly! BUT the ribbon rig teleports when the sine blend is turned on.
I did make sure to freeze all rot values for the joint chain, and freeze tran and rot value for joint binds connected to the ribbon.
Im starting to think maybe i messed up when constraining? Im not sure how to fix this

Any help is appreciated!!
