Atlas
Game freezes on cash-out but you can reboot the machine and enter the operator menu or you can still play the game just not cash-out because it will freeze up.
If you have this issue:
Reboot the game
Enter the operator menu right away when the game boots up
Change the printer type to no printer
Exit the menu and return to the game
Go back in to the menu and set the printer to the correct printer
Exit the menu and print the ticket it should work now.
If the steps above do not resolve the issue you will need to ram clear the game.
To ATTo fix the issue (assuming the game is using a FL printer) replace the printer with a Ithaca 950.

Had a tech say they ran the NCFI tool and it cleared this issue.
