The servers went down today, August 20th, 2015 for a hotfix and when they came back up players noticed that their tomes were no longer applying to their characters. A short time later the servers went down again to fix this issue. Cordovan explains what happened here. Any progress that was made during the brief period the game was back up will be lost due to the developers having to roll back the data to before the update. The servers are expected to be back up sometime in the afternoon of August 20th.
On a lighter note it was pointed out to me that the rogue trainer in the Marketplace seems to be practicing her craft. She can be seen picking the pocket of the tourist listening to the bard play music. Could be that the bard trainer could be in on it too. Seems like something a spoony bard would do. Check out the screen shot above.
