So, here's the problem. And this is why I was drawing a blank for a minute. You put the arguments like -nogui in the serverstart file. I DID do this part. I thought maybe I was just being dumb and forgot to point the multicraft client to the bat or sh files, but that's not what happened. The ftp client fails every time I try to upload any .bat or .sh file. This is clearly intentional. I don't remember if mcpro was the same or not, but I was but a pup then and wouldn't know.
So, there must be a way within multicraft to include those arguments. But I can't find it. This is either my fault for diving neck first into things I know nothing about and missing the fundamentals, or these site runners are either up to something or incompetent. I've put in tickets days ago and I didn't get a response until I called them out for the delay, and all they did was pass their issue on to a different department that never responded (a refund request for accidental double payment) and someone who asked me to run spigot commands when I'm not running a spigot server.
