Simulation Error with MTRL_KR6_R900 ?

[corohello]

Hi there,

Is anyone else having trouble with the MTRL_KR6_R900 robot from the Robot Library?
The robot looks correct in the beginning but when I simulate the program, the joints separate like the screenshot below.

I tried to insert a new KR6_R900 Rhino model by copying a new robot .xml and .3dm into the Documents/Robots location but I'm not sure how to load/update the library in Grasshopper so that the new robot shows in the dropdown list. Unsure if I am going about this the correct way?

Any help would be much appreciated!

Thank you.
