Players of the Open Beta of Neverwinter were sort of compensated for their lost time with the necessary roll back that they needed to do for an in-game bug involving Astral Diamonds (one of the game’s currency for items & within their Auction House system).
ZAM did a write up on the mishap here
This is what players have received in-game as a compensation for the bug that was discovered with an RP sense of return for the player to have to remember the event that took place. You were also rewarded a title of “Caturday Survivor” from the roll back.
The items included in this roll back event RP package are shown above in the bottom 2 pictures. Some of them are helpful game items & some are just memorabilia from the event.
Here is the news post from the Neverwinter Team.
