after this last maintenance, i'm sure a lot of you will be curious as to what is really happening around them.
if you don't know, many deleted characters from diablo 2 were rolled back into existence. seemingly, a lot of these characters were rolled back far enough that they are re-stocked with old gear that they have long since sold/xfere'd/deleted.
this means quite a few "copies" of items now exist.
now let me tell you why this is so scary. first, please do keep in mind that there is no difference between original and copy. they are both original, they are both copies.
example: you purchased an item. doesn't matter how you paid for it, the big thing is that you now have an "item". it has been 8 months since you've purchased this item and have had no issues.
you might now start having an issue. it is possible that the person that sold you this item, had his account rolled back. now both of you have the same item.
blizz has a few protocols for identifying and erasing copies. the most known being a "clash" in-game. this works as blizz does a check with each save/exit.
however, this is not the only protocol. there are lesser known server checks that will clash items in games sharing the same server number. this means, you can be clashed at any time, anywhere. the "item" you bought 8 months ago, now has a possibility of having a copy in existence.
i've also heard a game can hop along different servers if it's up for a long period of time. i have not tested this myself, but if this is true. it would mean you are doing more random clashes in longer existing games.
trade carefully. if you care about other people you've traded with at all, get rid of any items you sold to someone and got back from this. you could very well end up clashing the other out of existence.
good luck everyone. i'd suggest not going "all-in" on items right now.
