Bug / Crash Unstable rope only when interpolating in build

[cfinger]

First, thanks for the great asset! After building my own rope using joints, I am impressed with the behavior and performance of obi rope.

I'm currently having an issue where the rope behaves as expected in the editor but on play mode it isn't stable and flies everywhere. 

Set up: 

• Rope with 2 attachments, one static, one dynamic.
  
• Attachments are outside of colliders, and both control points are the same phase as the nearest collider
  
• Using Burst
  
• Obi Solver has interpolate selected 
  

When I make a build, the rope will fly everywhere, despite the attachments behaving as expected. If I turn off interpolation, the rope looks fine, despite a ton of visual jitter (the static attachment is on a moving rigidbody). 

I would really prefer to use interpolate to avoid this jitter. Any ideas? 

Thank you.
