Annoying blue walls.

[Trollslaughter]

Whenever I get a Core game data is being downloaded while playing in game a blue wall always appear in front of me and stops me from going where I want to go, its rly annoying and I don't know if it is a bug or a just a annoying stuff by blizzard. is anyone else having this problem?

[Subliminal]

It's not a bug. It's because the data is still being downloaded.

Wait for the download to finish first before playing if you think it's annoying.

[uzumati]

the game is trying to download data for the area your in. Once it has completely downloaded all the cata data the blue walls will stop.

This blue wall is area which is not downloaded. It's understandable that you can't get there. Just do as they say in the downloader - turn off the game and resume the download
