Hello snattack, 

We´re having a hard time to reproduce this here, with any Kontakt libraries. 

Does it still happen 2 times in 3 months? Any hints on how to provoke the behavior? If yes, it might be worth a shot to try that approach in your sequencer (I also think this is a bug on Logic's side of things).  

What do my colleagues at NI have to say about this, did you contact them?

Best, 
Paul

Are you using a VNC program like Remote Desktop or Tight VNC? If so, maybe they could be the issue?
