last night I was in a mission and waiting for my target to get in a taxi, from a distance. I look to my side and see a person's head sticking through a wall near the ground (so their head was about 1 foot above the ground, coming through the building). It looked like they were trying to walk forward, and then the were launched up, possibly into the sky possibly just onto the roof, as if the game was correcting the mistake or something. very strange.
