Um..I just read the last Liberator GM post....and.....the Liberator didn't just stop. Dan did drop out of warp....but only long enough to change course. The Liberator then went back to warp.
And with the Jacara going between Warp 2 and 3, they'd still be a bit behind the Liberator...which is crusing at Warp 4.
Understood. The GM post has been modified :)
