Dear all,
This is to announce that we've found a bug when you load the same game multiple times, ships don't seem to be pulled into the wormhole.
This is a timing bug and due to the way it was loaded. The resolution is likely to require a start of the mission if there're any ships stuck at the wormhole.
We apologize for this and will deploy a patch as soon as possible.
P.S. This does not apply if you play normally, save as many times as you want ... and load just once when you first play.
Regards,
Jeremy
