During making a new mod of my creation using command blocks I came across a very strange bug. When I spawn the creature in, everything is fine, but when I hit the creature, my hole screen is tinted red. At first I thought it was a super secret setting but I'm still not sure which one would do so. This is a very strange bug and hope you can fix it. Thank you <3!

What I expected to happen was have a simple battle against this powerful creature.

Instead it created an attack I certainly didn't program. The entire screen was tinted red, within Minecraft I might add, and when I closed minecraft and reopened it was fine until I hit the creature again.

Steps to Reproduce:

1. Spawn the creature using the following command –

 /summon PigZombie ~0 ~1 ~0 {Equipment:[{},{},{},{},{id:skull,Damage:3,tag:{SkullOwner:}}],CustomName:"Ender_Mage",CustomNameVisible:1,Attributes:[{Name:generic.maxHealth,Base:45},{Name:generic.movementSpeed,Base:0.2},{Name:generic.attackDamage,Base:18},{Name:generic.followRange,Base:20}],ActiveEffects:[{Id:21,Amplifier:1,Duration:999999},{Id:14,Amplifier:1,Duration:999999},{Id:10,Amplifier:1,Duration:999999},{Id:11,Amplifier:1,Duration:999999},{Id:1,Amplifier:1,Duration:999999},{Id:5,Amplifier:1,Duration:999999}],Silent:1}

2. I also have other commands set up in the world like, the first extremely fast clock using commands, as well as particles constantly being teleported to the mob.
3. Hit the mod and BOOM, tinted red screen, weird right?
4. I also noticed a strange glitch when screen shotting the evidence, my body was teleported to the particles (UPSIDE DOWN) <---like what is this? When I came out of the game the minecraft background was hazy. This glitch is BAD!!!
