I get this error when using basicly ANY non-base game NPC that is human:

[Fedhoria - Active Ragdolls] lua/fedhoria/modules/stumble_legs.lua:337: attempt to index local 'phys_torso' (a nil value)
1. PhysicsSimulate - lua/fedhoria/modules/stumble_legs.lua:337
2. unknown - lua/entities/active_ragdoll_controller.lua:218 (x22)

Its really annoying and i dont know why this is happening.

This seems to happen with nearly ALL VJ NPC's and even the Resistance and Combine Reskins.
