Battle .net app says it needs to update WoW, but says: “Whoops! Looks like something broke. Give it another shot. “More help: BLZBNTAGT0000138F”. I cannot update WoW. Also, before this, my game heavily bugged out (did not allow me to interact, mount, hearth, etc). It’s not my internet connection, that’s stable. I think it’s something on Blizzard’s server side.
Edit: I think it was a temporary issue, I’m able to log in again.
