Antimatter Cordon

I was just flying the antimatter mission where you have to defend the antimatter freighter and dock to it to keep it charged. (I hate this mission, BTW) I had destroyed all of the marauders, and the antimatter field was up to 100%. Nothing was happening after that. The freighter wouldn't move. As soon as I tried to fly away, it blew up.

What gives?

Try reformating with it after all the Marauders are dead and the containment is 100%.

This was no disciplined march; it was a stampede-- without order and without a goal, six million people unarmed and unprovisioned, driving headlong. It was the beginning of the rout of Civilisation... of the massacre of Mankind."
