Bug / Crash Issue with Grasping ObiRope Using Two ToolsGood morning, I’m encountering a strange

[alicecatalano]

Good morning,
I’m encountering a strange issue with grasping a closed-loop ObiRope using two tools. My goal is to grasp different points on the rope with each tool, without using constraints.
The Problem:

• If I grasp the rope with the left tool first and then with the right tool, everything works as expected. Both tools hold their grasping points correctly.
  
• However, if I grasp the rope with the right tool first and then with the left tool, the following happens:
  • The right tool keeps its constraint but the grasped particle shifts to a position far away from the intended grasping point, while still visually connected to the tip of the tool.
    
  • The rope responds to tool movements but maintains this unnatural offset for the right tool.
    
• The issue only happens when the right tool is the second to grasp, and it occurs inconsistently.
  

I’ve attached an image showing the situation. The rope becomes distorted, with the grasped particle connected incorrectly.
What I’ve Tried:

• Confirming the attachments are created dynamically at runtime without pre-existing constraints.
  
• Checking that particle indices are updated correctly during grasping.
  
• Ensuring the tools have unique attachment components.
  

Image Explanation:
In the attached image:

• The left tool is holding the rope correctly.
  
• The right tool exhibits the described offset issue when grasping second.

Question: Why does this behavior occur when the right tool is the second one to grasp? Could this be a bug in ObiRope's particle attachment system, or am I missing something in the setup?
Thank you for any insights or suggestions!
