If a AI controlled unit enters/exits a vehicle that is attached on a man class unit, the getin/out animations do not play smoothly.

Torso = class Tank, Legs = class Man, Torso attached to legs.
Primarily a modded content issue, but vanilla vehicles are also affected so this is technically a engine bug?
Player animations seem to play smoothly in all cases and all animations play smoothly if vehicle is attached to a another vehicle.
