L4D2 Gestures

[Portalboat]

In a attempt to get the gestures working for the original L4D survivors, (they weren't working before, with a "Gesture *name* not found!) I am getting this:

StartGestureSceneEvent tried to start sequence 'TeenAngst_gesture_pointLeft_quick' (874) without Activity!


There IS activity, I called the gesture by pressing the "Look" text on the radical menu. How can I fix this?
