Game just closes/vanishes when loading a new sector

[nanimonai]

Hey,

 

really enjoying your game so far, but since the last patch it got buggy, had no problems before.

So whenever I try to join my friend, I get a steam-message telling me: "Spielstatus nicht verfügbar." and then nothing happens.

Also whenever I try to jump to another sector, the game just vanishes, as if it was never open to begin with. No error-message or "Avorion has stopped working" or anything like that.

So, this bug might be a problem on my side, since I have the same "vanishing" with the game Everspace, this game also vanishes when ever I jump to a new sector...

However this only started with the new patch, before I had no problems at all.

I updated my graphic-driver, didn't help.
