When you’re an adult, you’ll expect a lot less in life. Wowhead should have a notice that D2R is 'play at your own risk'

We’re sorry for the inconvenience this rollback caused to you, however, there’s no way to recover the levels lost due to these rollbacks.

This is the response blizz has posted about rollbacks: And it rolled me back to way AFTER I got my cube. What good are the recipes when the cube can just VANISH? ANOTHER 'rollback' and this time i lost several hours of play AND my cube is gone. One important thing to remember is you can use your Cube for repairing gear! These Transmutes can be used to obtain new jewelry pieces, Potions, as well as recipes for upgrading or augmenting gear. Our Horadric Cube Recipe Guide will give you a breakdown of all available Transmute recipes in Diablo II: Resurrected. Make sure you know what you're making before you combine! If you don't have the right items, it simply won't do anything. To use the Horadric Cube, place the correct group of materials inside the Cube and click the Transmute button at the bottom. For this reason, some players short on stash space will use the Horadric Cube as temporary storage, tossing items onto the ground while they do their Transmutes. It takes up a 2x2 space but has 12 slots inside.

The Horadric Cube can either be carried in your personal inventory or in your stash (most people keep it in the stash). Since it's available on Normal mode, you will get the Cube early. It's located in the Halls of the Dead, guarded by Bloodwitch the Wild. You will acquire the Horadric Cube as part of your questing through Act II.
