SW3 NESF Mission Blockade: Mothership blows on return to Elio

[mcole]

Hello,

I've played the NESF mission to break the blockade to Dionisys and on my return to the Elio system I first see six ships marked as hostile (NESF) and after a few seconds everyone is marked hostile and my mothership is destroyed. Some times Alexandra starts to speak and dialog develops, but after the dialog ends the Mothership blows as well.

Does anyone have a suggestion?

ciao,
