We found this bug with my brother accidentally during the passage.
 What should I do to see this error:
 1. You need a second joystick and enter Minecraft through it.
 2. The first player must show a crossbow in his hand, or summon a robber already with a crossbow.
 3. Look at the screen of the second player at the object we need, namely, it may be that the object is meant, either a player or a robber.
 How should it be more correct:
 The second player should see the location of the arbbow as well as the first player
