If a player and a nearby mob perform a long-distance teleport using the teleport command at the same time, the mob will go crazy. Specifically, the situation is as follows. 

• Mobs can move, but they become invisible and sound does not play properly.
• Unlike the "effect : invisibility", the armor equipped by mobs also disappears.
• We can deal damage with a bow and arrow, but the player's melee attacks won't hit the mob.
• It will be knocked back by bows and arrows, but will not burn by "Enchant : Flame".

And other conditions. 

• It occurred at a distance of about 300 squares or more.
• Confirmed on Windows version and iOS version.
   
• This did not occur in versions prior to 1.21.30.
