Sometimes after finishing a mission and after my character teleported back to the ship, I'm stuck on the map. The UI is all greyed out, but it is still responsive and desplays things like current HP when I hover over the HP-bar. However I cannot open the menu or do anything else beside hoving over things with the mouse. 

The loading screen will not come and I have to crash the game manually ... which also mean I need to restart my entire PC since I cannot log back in after a crash.
