From master clue scrollsEdit
- On release, there was a bug where the casket would not disappear when the casket was opened. In order for the casket to not despawn, the player's inventory had to be set up in a specific way with a specific final clue step and challenge. This resulted in a flood of valuable items, and was quickly hotfixed after discovery. Players who abused the bug greatly were permanently banned, while those who used it less were given a temporary ban. The items brought in by this bug were manually removed from the live game, and players who bought the illegitimate items were refunded the price they paid for it.
