This has happened to me many times, both on the ramps leading up to the city and on the bridges that lead out to the rest of that map. My raider will be driving with my cleric as the passenger. Once I get to whichever npc I need, I hop out of the cart on the raider's client. Naturally the cleric comes out of the cart at that time too but she always somehow ends up stuck kind of under the ramp or bridge. These ss are from earlier today, while going up a ramp to the upper level of the city
