Help Change obi rope attachment target realtime with script

[Adammm]

Hey! I was trying to change obi rope attachment the other day with script, and I couldn't make it happen. Whenever I do it manually in the inspector while playing the rope snaps to the new target position. But if I do it with script (just change the attachment script target to new transform), it changes the target but won't change the position nor do anything. 

Can somebody help me with this and if fix the issue?
