Thanks Maze. Wasn't thinking about ports. I'll just have to figure how to get another machine to let me install or get a copy and paste job to work, and remember to have 2 different clients to connect with.
Wait, so that wouldn't matter anyway no matter how many computers, can only have 1 lan server running at a time it sounds. That kinda defeats the reason for making a test server, not having to keep hotfixing etc or restarting the one everyone plays on.
Oh, but I'm not a bruh
