Shukaku: There is a bug in Cleopatra where, if you play a mission that has troop carry over, and you don't build the forts immediately at that point (ie, you quit out of the game, or save/reload), the troops will not enter. The only solution to this is to replay the whole previous mission and rebuild the troops: reloading the previous mission and playing again will not work.
EDIT: nwm, I understood it now.

Sorry, I have another question - so I have to replay the first mission in one "sesion"?
