Retrieve the red star - danger close ranger mission BUG

[Kvesty]

I cant retrieve red star neither after restarting game and playing it again (tried 4 times). I cant continue in campaing because of this.

Getting this bug too, I had to glitch the diamond out of the box by jumping on the table and shooting the box from above w/ the revolver. then I could open the box and grab the diamond.

Make sure you're aiming straight down at the case and keep spamming the revolver until the diamond jumps out of the box. That's what worked for me.

Unfortunately still happening. I'm not sure if I want to give up or look for more tips on a fix.
