Guardians with generic.followRange of 1000 cause immense lag and errors

I think you can close this as it is like at MC-60182 also it throws strange errors out

WARNING! Do not test this in your normal world, please create a new one

Perform this command:

/summon Guardian ~ ~ ~ {Attributes:[{Name:generic.followRange,Base:1000}]}

This will cause

1. 1. 14w25b Error 1

   2. 14w25b Crash
      (I summoned it in a river but it seems not to be necessary to be in a river)

   3. In 14w26b will cause these:

      [22:00:40 INFO]: Client> [22:00:40] [Server thread/ERROR]: Tried to setBlockAndData(minecraft:torch/0) but it's an invalid state. Defaulting to minecraft:torch[facing=up] instead (minecraft:torch/5)
      [22:00:54 INFO]: Client> [22:00:54] [Server thread/ERROR]: Tried to setBlockAndData(minecraft:furnace/0) but it's an invalid state. Defaulting to minecraft:furnace[facing=north] instead (minecraft:furnace/2)

      Also when you summon one riding a witherskull:

      (I did this in a superflat world)

      /summon Guardian ~ ~1 ~ {Riding:{id:WitherSkull,direction:[]},Attributes:[{Name:generic.followRange,Base:1000}]}

      you should copy this in a commandblock

      "14w25b Error 2" happens

*Also the shooting animation doesn't appear when the attacked mob is too far away
