Upon further testing, could reproduce this using the Burst backend with world-space wind enabled in the solver, regardless of the world-space inertia values used.
The problem lies in the aerodynamic constraints: when using too high drag/lift values (you're using 3 and 1, the defaults being 0.05 and 0.02), the relative velocity between the particles and the surrounding air can induce very high acceleration.
Could you verify that disabling aerodynamics on your ObiBone circumvents the issue?
Will fix this asap, the share a patch. Thanks for reporting!
