Hello, I see some posts about 1.17.1 and beyond jar files are just no longer there. And that is how it is supposed to be. I am having trouble because my host uses the jar files to start the servers. Is this something they have to fix and not me? I am trying to get a server running with 1.18.1 and I was going to do it how I've always done it and the server jar file no longer installs when you install the server portion. Any help is much appreciated
