Illogicality (pseudo-nonlinearity) (Elex)

In one of the "fake documents" task, we need to go to the clerks, find a cooper and give a fake document. I gave the document, Cooper ran to the hunter and their gang.

But here's the question:

- I warned the guard in advance that fake documents were being made not far from them - he took this into account. At the same time, he missed Cooper (no questions asked, even the cast did not work)
- When Cooper returned to the hunter, he ran past the whole gang and stood behind the house. What is it like? Like he didn't give a damn about everyone?)
- I killed Cooper in front of the hunter and their gang - they started aggroing. As soon as I fly away, go back and talk to the hunter, a dialogue appears that Cooper is dead, but the hunter no longer aggro on gg and says that the clerks are to blame for this... how?)0)) 0_0
