@lResxt I don't necessarily need a dedicated server, no. I primarily just set it up because I wanted to do some mod development. I've been programming for almost a decade now. Figured it'd be fun to see what I can make in bo2.
I tried that mod menu before, but I have the same problem with trying to give people host. They'll be able to open the menu, but then it will bug out. No items show up, the menu freezes on screen, etc. That mod menu also causes a crash for some reason.
