Here's the video of what I'm experiencing: https://vimeo.com/519484422
The jittering looks like a collider problem even though it shouldn't be pinning the particle inside, especially given where the particle seems to pin. Hopefully it's obvious when I'm grabbing the rope, as I'm in the middle of reworking the hand animations, but it should be clear that while the particle follows my hand it is nowhere near the actual position, or even the original position it was in. It gets closer as I rotate my hand, but then it jumps to the other side, still far away.
