This mod makes Casing Mode act like Civilian Mode in terms of detection, so enemies can only detect or get alerted by you if you mask up
This mod doesn't make all things easy, for example Car Shop has a scripted restricted area where even if the guard doesn't detect you, trespassing will make him get alerted as it puts you masked up.
If you just use this mod, casing mode would only be a one time thing, you are free to look everywhere with guards dont detecting you (except Car Shop) but when you mask up, you better sneak around.

DON'T PLAY ONLINE, AS IT MAYBE CHEATING OR CAN CAUSE DESYNC ISSUES
