Lost Corpses and Item after died many times in UBER

Hello, my character is DRAGOON. i tried Uber and died about 20 times with Duriel potal , i decided to log out and get all of my corpses. However, there are only one corpses left and I lost all of my valuable gears in other corpses. Please reverse and retrieve back all my items, thank you

Woof… Sorry to hear about that.
Though to me it sounds like a game design… The number of corpses is set by the game.

Here is what “The Arreat Summit” states… it was the D2 Info source back in the day… Would link… but they won’t let me… like sriously… wtf!! Welcome to 2021…

Multiple Corpses/Losing Items!
A player may have up to 16 corpses.

Realm Characters: The corpse with the most gold value (in items) will be saved between games. So keep this in mind when putting on equipment to recover your corpse. Your original body with your equipment should save unless you manage to equip yourself with a greater value of equipment, die, then leave the game.

Open Characters: Only your oldest corpse is saved between games. Make sure you go back and recover your original body with your equipment before leaving the game.

Warning on recovering your corpse
If you needed +Strength or +Dexterity items to equip other weapons or pieces of armor, you may have to re-equip these items manually. When you click on your corpse, the game attempts to re-equip your items to where they were before your death, but this depends largely on the order in which your items are picked up. For example, armor that requires more than your base Strength will not be equipped if the game attempts to place it before placing the item that increased your Strength enough to wear the armor. In this case, the armor will return to your inventory; if you do not have enough room, it will remain on the corpse. Check your inventory and make sure that all of your items have been re-equipped correctly.

Body Count
Having Difficulty recovering your corpse?
If you can’t find your corpse, or if it’s too dangerous to retrieve it with your current equipment, simply exit and re-enter the game. Your corpse, and all of its items, will appear near your starting point in town. The only drawback is that you will lose any gold your character dropped when he died and you will give up the chance to regain 75% of your lost experience on Nightmare and Hell Difficulty. This is a good option for Nightmare and Hell difficulties, in which death results in lost experience. The corpse will appear at your starting point, typically near the point where Town Portals appear in town: In Lut Gholein, this area is at the bottom right of town. In Kurast, it is next to Meshif. You should be able to find your corpse easily if you explore the town.

Character Saving/Loading and Corpses
Periodically, Battle.net will automatically save every character playing in every Diablo II game. Your character will also be saved when you choose “Save and Exit Game” from the ‘Esc’ menu. If you die and leave a game without retrieving your corpse, it will be placed in town at the beginning of the next game you join or start.

The character save data includes character Attributes, inventory, Skills, Skill hot keys, control configuration, Waypoints activated, the character’s corpse (if one exists), the list of completed Quests, and the contents of the character’s Stash.

Sounds to me that you just had too many out at once. There are certain senarios where you can lose your stuff and it’s by design.

I myself lost all my stuff cause of a bug/issue with the game…

So… even if your stuff is lost via legit (aka their issues) circumstances… it doesn’t matter… their answer is the same…
They won’t restore ANYTHING… characters… items… nothing… even if they are to blame.

Sorry for your loss, and take a look at the rules… though… tbh… it doesn’t matter if you know them or not… right now you can lose some or all of your progress without them taking any kind of responsibility. Why I’m waiting till they are fixed.

Save travels out there.
