How is this a duplicate of MC-94438? That talks about being on a server. This is strictly multiplayer. Etho from Ethoslab has discussed this problem too in one of his videos.

I found the problem. When updating the snapshot from 15w51b to 16w02a mobs with scoreboard objectives will no longer work. The testfor will testfor the mob name, but in the scoreboard objectives tab it will have to display the mobs UUID, and not the mob's name itself. I guess this is to prevent confusion between an Armorstand with the same name as a player.

So basically in 15w51b the testfor command would testfor a mob with a name for their name, while in 16w02a, to testfor a mob the mob UUID must be in the sidebar.

How I fixed it:

/scoreboard players reset ZombiesSpawned

Screenshot of this not working in my actual world that I need it for.

I attached a screenshot it has everything in it. I even created a new world to test it. I even attached me finding the Armorstand in chat

It doesn't just happen in the command block, when I type
/testfor @e[name=ZombiesSpawned,score_Zombcount_min=1]

It doesn't output that it found "ZombiesSpawned"

These are the commands:

To summon the ArmorStand into the world with the name ZombiesSpawned
/summon ArmorStand ~ ~2 ~ {Invisible:0,Marker:1,NoGravity:1,Small:1,CustomName:"ZombiesSpawned",CustomNameVisible:1}

On impulse: To set the armorstand's Zombcount score to 10
/scoreboard players set @e[name=ZombiesSpawned] Zombcount 10

On repeating command block that doesn't need redstone: Testfor the armrostand's Zombcount
/testfor @e[name=ZombiesSpawned,score_Zombcount_min=1]

These commands do not work. Yes I have Zombcount as a dummy objectives. These commands work in the previous snapshot, but not in 16w02a. No they are not conditional. Nothing is wrong with the commands I used.

You're all wrong I know how to use command blocks I have all my objectives, the armorstand has all the objective X=10, but the testfor block is not working. I'll show pictures. Make sure you guys are in 16w02a.

If this why my redstone/command blocks are lagging? As well as the mobs after I play for more than 10 minutes.

Why is this unresolved?

I deleted my .minecraft folder and re-ran minecraft, it works now, but It broke from updating from 1.7 to 1.8 snapshots.

I don't understand why this is marked as "Cannot reproduce". All you do it type the command into the chat in which you don't hear a sound. Are you playing on the right version of Minecraft?

What? No I used my iron shovel on dirt, and my Minecraft doesn't crash.

Crash Report

Confirmed. Was confused why t wasn't happening in my map, but I see now.

Also it seems that this may be connected to item frames popping off when opening up a world before this snapshot than loading it in this snapshot.

Still exists into the snapshots of 1.8
