So this has been happening for a while now at first I ignoredand assumed it would get fixed but it isn't so this is not happening for all maps but a few of them, (Including Simberia the free one Mojang gave out for free) It will say download complete, but when you try to go play the world it will look like this. (Look at the picture) So due to this bug I cannot play a lot of maps some of them that I bought it is very annoying please fix it

I bet no one will see this
