Bugs

 * Legion mongrels and NCR guard dogs may still attack the player despite their disguise, if they are hated enough by the associated faction. This does not occur 100% of the time however.(This is not a bug,the dogs are there specifically to sniff out people in disguises as are high ranking officials such as Rangers or Caesar's bodyguards.)
 * Rarely, a mongrel will be in the place of NCR guard dogs at the power station mirrior computers, only after you talk to Fantastic.
