Index used to refer to a weapon index I set for the program (Primary slot, 45 (Force-a-Nature) to be precise). It's been now rewritten for 3 slots for more testing purposes.

Yes, in both my Post_Inventory_Application & Player_Spawn hooks. Here is the full code of the program, I apologize for not posting it sooner:

        return;

    new slot = GetClientOfUserId(GetEventInt(event, "userid"));
    decl entityStorage;

    for (new i = 0; i < 3; i++)

            GiveWeapon(slot, MyWeapons[i]);
            PrintToServer("Slot %i does not match", i);

This force-spawns you as a Scout with the Force-a-Nature, Bonk! and Atomizer. They all do what they're supposed to (knockback, consumable/immunity and triple jump, respectively) and have proper skins, but, for example, the Atomizer still has the Bat taunt (that's how I noticed that the indexes differ in the first place).
