This might be purely circumstancial evidence, but in the last couple of days I've seen people merching some very unusual items, a few of which i've bought. I then see them only a short time later merching the same unusual item.
On the steps of Moradon on D1 there is a person called Rosehip merching a transformation totem and a large hacker+8. This morning I bought the large hacker +8 and tried to trina it (cos a +9 is actually quite sweet). It blew up. Ok no problem there, but I come back this afternoon and they are selling ANOTHER large hacker +8... It's the only large hacker+8 on the market and they happen to be selling it twice in one day, but didn't have 2 on the initial stand?
Yesterday there was a guy selling a LOT of +16/3 jewels. I bought a couple of 16str/3hp earrings. Unusually one of them was a "pearl earring" type. (Most +10 or higher are the "ruby earring" type, as that's the type which drops at +9). A few mins later he PMs me saying sorry he d/ced, do I want to buy more. I check his stand and he again has 2 +16sr/3hp earrings, again one of them is the "pearl earring" type. While I had his stand open and was looking thinking it was weird, he d/ced again... Is there some rollback bug they are abusing here?
The earrings didn't disappear during maintenance yesterday, so i'm guessing the server thinks they are clean (or they aren't doing dupe wipes every maintenance any more)
Anyone else seen this kind of thing going on?
