[QUESTION] Typo in VBD_solve_trimesh_no_self_contact?

[CliffieVanR]

In the no-self contact version, I see this: particle_pos = pos[particle_index] particle_prev_pos = pos[particle_index]

However, the self-contact-handling version has particle_prev_pos = pos_prev[particle_index]

Is the first instance a typo?
