YEEESSS!!!! I have thought up the ingenious and simple decision of a problem with TOP-things!!!!))))))
So! Idea:
Let there is an accidental meeting (only on special region of a world map) where it is for example BoS or the enclave on vertibird has got in accident.
And last survived there NPC to ask you to help them (to execute some quest) and gives you PA (or APA in case of an enclave).
From this point on time for performance of the quest starts to go.
And after (for example) from one about two days (if you have not carried out the quest (and after which performance PA vanishes, and you receive what that some compensation))BoS finds you, and kills where you would not be (both take away PA and goes down carma)
If the PA has got to other player (when the time was end, and BoS have found you) it is waited too with terrible death and take away PA, and goes down carma
What in this regard in general there are no ideas?
