A crack system divided into two places by the difference between the private official gangs and the normal gang, and it's only for special gangs to guess the correct numbers and crack the safes. Now let's come to the main subject, If the same is divided into two options for normal pbr f.e automatic and manual crack, then it doesn't make any senses for official gangs, If you remember when you are not in the official gang you will be warned to join any official gang to get access for crack when you enter the red marker in the bank yeah that's the main difference between gang and official gang, also if such a system comes I'm sure people will kill each other for manuel crack and that will disturb everyone..
