When dying in  Caves  or  Ruins, exiting the game right at the death moment will cause the Cave or Ruins world to reset. Upon reloading, the player will spawn in a new Cave or Ruins world and lose all the items along. 
 * This bug can be exploited to make rare non-renewable items such as Green Gems and Thulecite renewable without using the Wooden Thing. This bug works only if the player doesn't have any resurrecting structures active.

Jeez, thats quite a risk to take relying on a bug and then possibly deleting your world.
