Failed to Download Realms 1.1 bug

Failed to download Realms from 1.1 update.
Created a new seed when 1.1 launched and have not been able to download a backup of the map since.

Stays at 0% 'initializing download' for a few minutes then fails.

Tested on Win 10, Android Shield Tablet multiple times with the same result.

Major issue for realms servers.

I can still download another realm map which was started before 1.1.
