Steps to reproduce the issue:
Go into the nether in survival mode and when a ghast detects the player, sometimes the Bug will occur.
Expected result:
When the ghast produces a shooting sound and the mouth of the ghast appears to be open, then a fire charge is shot at the player.
Actual result:
The ghast will have the texture of shooting a fireball (open mouth) but no fireball is actually launched at the player and the ghast despawns. Or the fireball has a delay of a few seconds after the ghast has the shooting texture.
