While walking in the groove between a large rock formation and the side of a hill, character began to "slide" accompanied by a sound that would indicate sliding on gravel. I'm not sure if the character was animated to appear to be sliding. Once the character stopped sliding there was a short pause then the character flew through the air almost 100 meters, hit the ground standing, did not make a sound indicating injury and promptly died. Respawned close enough to immediately retrieve gear from dead character and tried this again. The same thing happened. Both times the character had an M4 in the hands but not raised or looking through optics. I've tried to replicate this again without any items in hands and was unable to.
