I was walking just a sec ago when i died just like that no creeper and i had full armor. wich makes it weird also was not fall damage or anything just plain death. (there was a lag spike and i was teleported back and died)

I believe this is a bug with Minecraft <object class="emojione" data="https://resources.enjin.com/1489581540/themes/core/images/emojione/svg/2639.svg?0" type="image/svg+xml" standby=":(">:(</object> It's been happening a bit and there really isn't much you can do. I'd recommend getting the mod "Rei's Minimap" and enable Death Point so you can go back and find your things.

It's fixed, Leo came and helped me <object class="emojione" data="https://resources.enjin.com/1489581540/themes/core/images/emojione/svg/1f642.svg?0" type="image/svg+xml" standby=":)">:)</object>
