Hi, I've started up a new server, but it has a time limit set. So I looked at the plans, and ultimate was cheapest one for the 24/7 server online, but that's the only thing I want, so I saw the custom plan, where i could get the 24/7 server uptime but not have to get the other things I don't need nor want to pay for, but when I try to update the server, there isn't a "custom plan" option. Is there one availabe or what?
