Well, when your in safe room sometimes and the safe room door automatically opens (MAGIC! :O), the infected spawn and rush into the safe room, including the special infected also (smoker, boomer, spitter, etc.) unless you type !raceon, all special infected are removed except jockeys but the common infected are still there
By the way, I meant in your first post. You wrote 2 different cvars for the first cvar line in your first post, to explain what the cvars are.
Jockey_racing_on = CreateConVar("Gamemode_jockey_racing","1", "Is Jockey racing on", FCVAR_PLUGIN, true, 0.0, true, 1.0);
I thought the cvar was Jockey_racing_on, not gamemode_jockey_racing
