Is that really a thing when you die in adamantine cave , whatever you found after killing alphas or the boss, it disappear ???? What is this ??? I hope is just a bug because this is frustrating after hours spent there .... Lost everything

Everything is really so, this is a PvPvE location, which involves a battle between players. When you die, you lose all earned uncleaned treasuries (those that you have already cleared but not opened will not disappear from your inventory).

All chests that have fallen out of you are equally divided into three parts:

1) personal - you can return them if you come to the same place where your hero died.
2) general - these treasures can be picked up by any player who will pass by - it can be you if you return before someone passes by,
3) the disappearing part.
