If you use automatic mod and game updates, you can change the language of in-game countdown messages. The selected language is also used by the Restart and Stop (5m Warning) actions.
- Next to the Start, Stop, and Restart buttons, click More.
- Click In-game announcements language.
- Select English or Czech.
- Click Execute.
You can also set the countdown before a restart to between 5 and 15 minutes and the save period after all players are disconnected to between 1 and 3 minutes.
Schedule the task early enough to include both intervals. For example, for a restart at 16:00 with a 10-minute countdown and a 2-minute save period, schedule the task for 15:48.
