Ok, you tell us...

Important notice, please read before posting in the support section

This plugin does not re-launches your server after it was shutdown, because it is not possible. You will need an external solution to that.

Perhaps you could possibly tellus what OTHER SOLUTIONS you would recommend?

Or perhaps you could do something like this within your code...

ConsoleSystem.Run(ConsoleSystem.Option.Server.Quiet(), $"restart {seconds} {message}");

... with the time set to the value set in your mod without any message?</p?
