Help Weird behaviour

[dhon2407]

Hi, I tried to create a simple rope with hanging object. I works as expect on the test scene, but on my game scene its acting weirdly.

Obi Solver, Obi Rope, OniCollisionWorld are on prefab. On my test scene the prefab is already on the scene hierarchy, but on my main game scene the prefab is instantiated on runtime.
