# Observed issues 

 - The game does not exit cleanly from the game menu and screen artefact gets stuck on display 
   It is better to [press] command+tab and navigate to the terminal and ctrl+c from there for exit (same the game first) during game 
   If the screen still gets stuck, in the terminal from where the game was launched type logout or logout -f , this should clear it. 

 - Multiplayer crashes and does not work
