I am using liggghts-with-bonds and trying to perform an indentation. Unfortunatly the bonds suddenly break shortly after they are created(5519 bonds are created at timestep 50000 and they suddenly disappear after timestep 52500). They are not even under any stress. The torque in the bonds just before they break does not nearly reach the maximum. I tried playing around with the relevant parameters but can't produce significantly better results.
What am I doing wrong?

Looking into it
Trying it on my machine and it worked in LIGGGHTS 3.6.0, but not in 3.3.0
I did get it pass the point it was breaking for you after reducing the time step to timestep = 0.000005
