No effect from handles nor pin constraints

[Evgenius]

Cannot reproduce here, both handles and pin constraints work in any particle. Handles simply set the particle's mass to infinite, so unless there's something else setting the inverse mass of the rope it should work fine.

If you upgraded scene from 3.x,  did you re-create the rope?

It's a new project with freshly imported new Obi plugins. I have two ropes attached to the object. But with identical actions to pin them, sometimes one rope attached, sometimes none. I'm pretty experienced with ObiRope, I done that hundred times. But this time I somewhy have these problems. Actions:
1. Initialize rope.
2. Fix one end.
3. Create obi handle for the second end.
OR
3. Add pin constraint to second end.
4. Link Object's ObiCollider to pin constraint.
(After playing scene pin constraint lose link and becomes None)
