Trade Scam / Bug?

I bought Yen’s blessing from [Redacted see ticket US101730534]
All 4 stats were crit
98 all stats
34.5% movement speed
52.5% resistance to all elements
18% resource generation

60% on unique ability.

I bought them between 4:42 and 4:46pm ET on October 22. They showed up in trade window, they were still there when I accepted.

Even after trade completed, they were in my inventory

I left party and they disappeared from my inventory

I rejoined party, they showed back up again, so I put them in the stash (I already had the exact same pair of boots in there that I bought at 4:28pm from someone else).

Left party, boots disappeared, relogged, boots disappeared.

I think I got scammed and there’s a bug in the game. I seen them in my inventory, I could hover over them and everything but would appear and disappear from my inventory.

I talked to the user (language barrier) and he was able to try trading them again (he still had them to trade, unless he had multiple pairs), but he wanted the gold again.

Can you please investigate into possible trade scam / duping.

Thanks,
