One in a half week? Seriously? What if it didn't just effect new players? And no one could play the game, would 1 and a half weeks be ok for you? I've played a lot of mobile apps and seen a lot of game breaking bugs, I think 3 days is the longest they have gone unfixed. Its a business. We are the rare few that actually cared enough to come to the forums. I would guess 90-95 percent of the new players, realized the game was unplayable, deleted and moved on never to visit again.
Most of the time a hotfix is done next day or the day after and doesn't even need a patch. But i've seen next day patches to fix something a major patch broke. I'm pretty sure a hotfix doesn't require the same window a major patch does.
I'd guess this gets fixed today or tomorrow anything else would be devestating for them. Imagine with the reviews start rolling in for the new patch, they are all going to be 1 star because no one can play it. That will have long term effects.
