I have an ark server with ya'll and it's great! I wish it was possible to set up a restart every night at 4 am. Right now I can choose every ~12 hours, or 20 or whatever, but I can't specifiy what time to restart. Is that something I need to contact a staff member to do to my server?

Yes you can absolutly set this up in the sceduled tasks tab on your servers, among other things. I have my restarting every day, every 12 hours. 

I want my server  to restart at 4am every night. This does not sem to be an option, as I can only choose every "12 hours, 13 hours, 14 hours" etc. Not a specific time.
