End of the rope! Match position

[Renman3000]

Hi there, 
So a peculiar issue that I can not solve.

Code:

Vector3 posEnd = obiRope.solver.positions[i_lastParticle];

So some background, this is running on an instance of my own Class, TentacleUnit, of which I have a half dozen in an array. Despite double-checking and rechecking that each instance of TentacleUnit is referencing its own obiRope, the position being reported is one position, across all units. 

Is there any reason, you can think of where calling one instance of an obiRope.Solver would imply this across all?


Thanks
