1. A bug in our authentication gateway caused some facebook logins to route to random accounts. We are still assessing the damage here, hopefully we can just help out everyone who was affected instead of rolling back the entire system, but we are not sure yet. We THINK we have identified the issue, and we have a check in place to determine if it happens any more.
2. [Update: This is fixed!] Our latest iOS release includes a bug that causes some issues logging in or registering for a new account. A fixed build has already been submitted to the App Store, so if you can't login it will be fixed in a few days.
We were hoping to get some new content out this weekend, but the fates decided we needed to fight another battle first. So, please look forward to some actual new stuff after our minds recover from this fiasco. We will be kicking Deepworld back up a notch with some new marketing and updates very shortly!
