Okay, there is a button that can apprently disable loadout restrictions. When I disable them no-one can spawn with the weapons the gamemode provides, and the restrictions still apply to the Q menu.
For example, if I had a loadout called test, which had weapon_glock. Then if I applied this loadout to the group Admin, admins would spawn with glocks and can spawn them from the Q menu.
If I then disabled loadout restrictions, admins wouldnt spawn with any weapon whatsoever, however they couldnt spawn any guns in the Q menu, apart from the glock.
I would like it so if you disabled loadout restrictions, you could spawn anything from the Q menu, and can spawn with any weapons that the gamemode gives you.
