      Arrows with negative damage can crash the game on hitting an enemy.

      This crash is strange, because crash seems to be dependent both on just how negative the damage is, and on the distance from player to the hit mob.

      How to Reproduce:

      1. Place an Always Active Repeat Command Block anywhere in the world with the following command inside:

      execute as @e[type=arrow] run data merge entity @s {damage:Xf}
      

      The exact value of X determines if the game will crash.

      2. Place and immobilize two Villagers, one 5 blocks away from the player, second around 25 blocks away.

      3. Shoot a villager with the bow. Be sure that the arrow will be in the air for at least one tick for the command to work.

      4. Depending on the value of X and which Villager you shoot, the following things should happen:

      X = -1.0:
      Near Villager: Game Doesn't Crash
      Far Villager: Game Doesn't Crash

      X = -1.4:
      Near Villager: Game Crashes
      Far Villager: Game Doesn't Crash

      X = -1.5:
      Near Villager: Game Crashes
      Far Villager: Game Crashes

      For all X lower than -1.5, game always crashes on hitting any of the villagers.
