Fixed #6: level vjun1 crashes when load game

if a new map (level) is loaded the AI needs a few frames to spawn all entities (frames = 10)
this is very important for cinematics, because some script access this entities created by the AI

if a savegame is loaded the AI entities are not needed and in fact can even crash the game
so we just update once (frames = 1), because zero is not working.
