Egosoft appears to be sticking fairly well to a “one new patch per week” schedule as it attempts to wrestle X Rebirth into being a decent, playable game. You can see their ongoing progress in this thread, and also take a look at the latest patch notes (reproduced below) for update 1.20.
1.20 appears to include a few fixes for player-owned ships (trade ships in particular,) along the lines of “Fixed trade ships getting stuck after upgrade” and “Fixed player trade ships trying to trade with enemy stations.” I have no idea if the game’s economy has progressed beyond the horrible state it was in when I reviewed the title, but I suspect it can’t have got worse. Hopefully.
Anyhow, here are the notes from X Rebirth update 1.20.
