Here's the bug in a nutshell.

1. I cannot Join a friend's world, the World appears I attempt to join, but as soon as I get the "Locating Server" It just stays there forever, unless the Friend leaves the world or I give up.
2. I cannot Download there Resource packs, When you join and it wants me to download it's resource packs, I tap the download button, but it doesn't download it just stays like that until It says I "Disconnected from server".
3. This only happens on friends worlds, I can join and download Resources from a Server just fine, and I can download worlds from the Market place just fine, it's literally just with friends worlds, please fix this ASAP.
