Floating Mobs

When chunks unload, any villager or mob that was in a minecart is now off from it and floating, some villagers disappear.

I previously reported this but the intelligent guy who replied claimed I'd used barrier blocks to create the effect of flying, despite the fact I had barriers in my hand..

Hopefully this time you'll realize that I have better things to be doing then reporting fake bugs for minecraft? Please look into this bug as it's very annoying
