Bug mission in "That's rude" on Tome 6 Divergence Level 4

thanarak

I can not complete the "That's rude" on Tome 6 Divergence Level 4

It said that i have to point in the killer's direction.

I have tried to do this more than 30 rounds and it did not work.

Is it a bug? or i did something wrong. 

Can you give me any clue what happened here? I saw that many people have this problem.

I use Steam on PC.
