I was testing the speed of the bees by attacking the player (since this was changed) the bee stopped one block before attacking me and was only watching me, try other hostile mobs, the same thing happened, they stopped, but did not attack.

It does not happen with mobs that attack with projectiles, only with mobs that attack melee.

What I expected to happen was...:

The mob follows and attacks the player, so on.

What actually happened was...:**

The mob follows but stops one block before making contact with the player and attacking him.

Steps to reproduce:

1-Find a hostile or neutral mob.

2-It is the case that the mob is neutral, hitting it and walking away a considerable distance.

3 - Stand still and wait for the mob to catch up.
