Help obi rope Collison and twine

[Raymond]

I checked the code of the previous developer and found that he only used dotween to move the rope and PrefabUtility.SaveAsPrefabAssetAndConnect() to save the model as a prefab, I did the same thing, but did not get the expected result, after saving as a prefab, the rope the same as when it was first created.This has bothered me for a long time hoping to find out why,Thanks a lot!
