Neverwinter had a rollback to address an Auction House/Astral Diamond exploit. I only had one character that was affected.
Q: What happened?
A: Early Sunday morning a very small group of players discovered and abused a game exploit within the Neverwinter Open Beta that affected the Auction House and Astral Diamonds.
Q: What exactly has changed?
A: We took the Neverwinter OBT down for emergency maintenance, found the bug, corrected it and tested it. In order to fix the damage this exploit caused to the in-game economy, we implemented a necessary rollback of our servers to 5:20 AM PDT the morning of May 19, 2013. This means that characters have been reverted to the state they were in at that time, pre-exploit damage. That includes items, level, experience, etc.
We know that character progress matters in Neverwinter, so as an apology for the lost time and as profound thanks for your continued support throughout this Beta, we are putting together a package of items to give everyone. We plan to distribute this towards the middle or end of this coming week, possibly on Friday 5/24.
