Build and Shoot

Ever since I made the switch to pysnip, people have been unable to connect to my server. I can localhost connect just fine, but when I click on my server on the server list, I get the unable to connect error message. Yes, I have port forwarded and allowed an exception for my firewall. The console is working fine and runs everything properly, it's just that people outside cannot connect.

As a side note how do I get zombies to work? It wont run if I put it in "game mode" because zombies is an invalid game mode, and it just ignores it if I add it to "scripts".
