Hello there,
So it's been a while now, maybe a month or two, smoothrestart stopped working, basically the mod starts like it suppose, everything works perfect till the timer is up, that's where the problem accure, so the mod will turn OFF the server instead of the restart, I have to manually turn the server back ON.
Anyone is having this issue ? the server host is "Shockbyte"
Thank you. 

ConsoleSystem.Run(ConsoleSystem.Option.Server, “global.quit”)

That fixed it.
