Its a thing out of date on your computer I had it too here is a picture if this is what you men't : http://imgur.com/aF5A2tt,
I think they said it was an AMD graphics driver that was out of date(I might have misspelled it slightly).
Kumasasa I thought it was a bug I checked after what you said.
Kumasasa also I used to have 32 range render distance but one day it randomly dropped back to 16 for no reason why is that and how do I fix it?
Kumasasa but mine was fixed when well I don't know what I did and it said it was up to date.
Ender Dragon thats mainly all it is
Thats because that isn't even a real item golden apples only go up to 1 data not 2 so it has that texture because it isn't a real item.
That happened to me too but I only said it about the chest in survival I lost lots of cobble stone and dirt from it when I was gonna use it for a farm and house
Also it has no hit box you are looking right through it in the picture.
Thats because It wanted to fly to the center of the world to where its portal is into at specific x y z cords not the structure.
The last 2 were in the same spot just 1 without and 1 with.
Thanks and I just noticed that the one in my redstone world works almost perfectly but only during the day with around 1 mob dropped a second on average and gets nothing at night. The one in my survival still doesn't spawn a single mob with the entity count saying 0/1 during the day. Could the cold oceans be glitched with mob spawns not working?
