EDIT: I found out the problem was a few syntax errors in the JSON config files for the server. I ran them through JSONLint and it lit those errors up like a christmas tree. Everything works fine now!

A few seconds after the server loads, I get this error:

Error: lua/nsl_tournamentmode_server.lua:135: Attempt to call global 'SendAllClientsMessage' (a nil value)
Call Stack:

So far, i've triple checked that the server config files are the same as instructed here:

I use a text file to add to the command line options of server.exe

I have also unsubscribed to any unnecessary mods and deleted all physical folders in my %Appdata% NS2 Workshop files so they can be redownloaded fresh. Currently the only mod I have besides the ones described in the NSL server setup guide is my own Crosshair mod which only contains the crosshair.dds files

pls help ;_;
