And dont be stupid and tell me I didnt add the launch option command. I said it worked yesterday meaning that I would of had to of have that in or I wouldnt be able to. Also, I just checked and I have the launch option and the command "sb_all_bot_game 1" in (and sv_cheats 1 first because I have to for the command to work)

This is great practice at least for versus. Also for spawning 20 witches in the main path and watching the bot AI conflict lol.
