Apparently if you save a game and then finish it later it doesn't get counted as completed for badge purposes; just had that happen to Plus Journeyman 12. That's pretty bad, not gonna lie.
I agree that the Loading Video bug is quite disconcerning to have, but compared to yesterday's BotD game which didn't even work 95% of the time, this bug seems minor in comparison. The trick is to not press ESC but instead click on the "Skip Video" button in the bottom right: doing that shouldn't incur in any other bugs (or at least it didn't for me).
Some users graciously said it beforehand but it's kinda hidden in the middle of 2017: if you log off, the game will load normally. You can then log in again and play without any problem.
