For all the people who are still wondering, why the exact same things happen to Diablo 2 (and obviously its re-master aswell) for the past 15 years, here is your quick explanation.
Diablo2 Network code is the worst peace of software engineering ever invented. It is so bad, that many people suspected some “conspiracies” over the years in a way that, you almost have to assume, Blizzard (or anybody) is incapable the level of incompetence not to be aware of these problems.
Why do servers massively crash in each ladder reset at least once?
Because people figured, how easy it is to exploit the ridiculous network code of Blizzards Diablo2 client->server connection. They figured what to do, to crash a server.
That maybe a simple DDoS attack, it may be an exploit, even some weird things you can do in the game can cause a complete server crash.
The important point to understand is, that is standard procedure that all games that were running on a server, are getting rolled back after it unexpectedly crashed.
Roll-back here literally means, that when you enter a game, all your items in your inventory are getting stored in a database and whatever happens in the game, this data is getting rolled-back to.
So guess what people are doing year after year after year…, they are dropping runes, runes and more runes. After that, they drop some more runes, especially SUR runes.
Why SUR runes? Well, the geniuses over there at Blizzard, which already created this masterpiece of network code, they did another awesome job when it comes to keeping a track-record of cubed-up runes.
To make a long story short: There is no track record and no unique ids on cubed runes (geniuses…).
TL;DR:
When you drop a few SUR runes in a game to your best-buddy, then crash the server, you’ll end up having those SUR runes duplicated.
All you need to do then is, to cube them into a BER rune (which of course is worth a little bit something) and you’re good, no way of detecting your russian-hacker a**, because Blizzard does not keep track of runes origins.
So now you know, why this happens… again, and again, and again, and again…
