Something went wrong. The fatal miscalculation caught the base in a vortex of hyperspace breach, ripping the station apart. Some of the survivors were lucky to be left in still intact air-sealed parts of the station, their rescue was in time by arrived vessels from nearby Philadelphia station.
And even though there are some people survivors, the same can't be said about Interstellar Beacon station, which is now just space debris.
A time has passed, a week, a year... but nothing appeared at the point of destination in Bretonia. The two bustards and ripped parts of the station went missing and were never seen again.
