Can you get anyone who doesn't have access to the bro !hat command to delete the registered hat? In other words, a player who no longer has an admin flag that we have specified should delete the hat from the cookies because it no longer has that admin flag, and the hat no longer appears.
This cvar saves the hats, but if the player no longer has that flag, the hat still stays and does not go away.
If the player does not have the specified admin flag, the registered hat will be deleted.
