Bug in Arma Reforger tutorial campaign (version 1.3.0.25 Experimental).
There are two bugs in the tutorial campaign (in the mission "Heavy weapons") that prevent the tutorial from being completed.
First. When firing from an underbarrel crane launcher, one of the targets is out of sight (outside the training ground, behind the forest).
Second. If you go out to the shooting range (behind the parapet), the instructor will start swearing and demand that you return. At this point, the current target disappears (changes to the return point). After returning to the shooting area, the targets do not appear.
