The problem is in the voice files both in-mission and in the debriefing. The in-mission ones could be a simple matter of setting up the events to omit those saying that the Plato was destroyed and that you needed to protect the escape pods, then when the pods jumped. For a matter of anti-confusion however, there could be a text-only message, saying that the Plato had jumped successfully. The real problem comes in the debriefing, which states that the plato was destroyed, but the escape pods survived. Omiting those lines would be far more noticeable. There are 2 solutions to this. 1, use an event to self-destruct the plato if it gets to the node and all enemies are destroyed. Its weird, but it gets the job done. This is not unprescedented, as the Ramses will self-destruct if its disabled and disarmed, or if the Taranis is close to being disabled, disarmed, or destroyed. 2, if the Plato reaches the jump node and has not yet been destroyed, have 6 or so Basilisks jump in at long range and launch Trebs or Phoenix at it. These weapons do enough dammage to destroy the Plato in a few hits, and are uninterceptable. All is clean and dandy, except that it involves changing the mission slightly, but all solutions are changes in themselves.
