The level, forced movement, possessable, possessor and combat AI parts
are each read behind a flag bit (LWOLevelProgressionComponent::
Deserialize 0x00c63bd0 and the others). DLU cleared their dirty flags
when it wrote a construction, which goes only to the client the object
came into range of, so a change waiting for the next update never
reached the clients already watching: a level up, a mount or dismount,
a rail ride.
