Could not Loot Corpse

… I’m having a very hard time understanding what you’re trying to say here. My guess is: you died a bunch on your sorceress, couldn’t recover your corpse, so you rejoined the game on your barb to clear out some mobs and then tried to come back on your sorceress?

Anyways, regardless of what you did. D2 and D2R do not have any form of loot restoration. It’s not possible. Blizzard can roll back the servers by a few hours or a day or whatnot but that won’t be done for 1 person that’s only in extreme cases where they do that.

When it comes to corpses and death mechanics in D2, I’d recommend reading this post from MissCheetah:

Sorry for your loss. Good luck, and may RNG be forever on your side.
