MPEntityPhysicsFix ^{Version fabric1}

How to make this yourself in MCP/LTS:

1. Go to ~line 543 in Entity.class
2. Add in this line before the position setting code:

if (!this.worldObj.multiplayerWorld || this instanceof EntityPlayer || !(this instanceof EntityLiving)) { 3. End the if statement after the third entity position is set (3 lines after the if statement) 4. Recompile and reobfuscate 5. The fixed class will be called sn.class in the reobf/minecraft folder
