Sold Ninja A1 Helm Shire Helm now missing due to Latency in controls

[NightsRespite]

So, I was going through my inventory, cleaning everything out purposely skipping my Shire Helm to Sell all the extra gear from classes I decided to not use. I cut down my gear sets to 9. Then went back to my armory to sell my Ninja A1 Head Piece with the rest of the set for GC seals. Well, apparently, it turns out the latency screwed my clicking enough to sell not only my Ninja Helm but my Dark Knight Shire item level 260 helm as well. The items that take a week to get for end game gearing. I didn't notice at the time due to having a gear set of a gathering class on. Here's the kicker. I was an Archer and entered a dungeon. Cleared Satasha. Then was teleported back to a level 41 area where I was doing a Sylph quest. I aggroed the enemies right before I entered Satasha so when I returned I Immediately died being level 27 doing a quest requiring invisibility. I was sent back to Gridania where I then teleported back to the area where I died. Right as I entered the area where I died, I quickly switched to my Dark Knight gear set before reaching the level 41 monsters again and re-equiped it. I then noticed something about my characters head. I look closer. MY SHIRE HELMET IS GONE. The one I had right before I entered the dungeon for my Dark Knight. Well, long story short, I came to the conclusion I sold my helmet without realizing it when I was switching my gear sets around. How did I not notice you ask? Well, I was checking myself to ensure this didn't happen but apparently thanks to latency with servers I must of clicked that one extra time to not only sell my Ninja A1 head piece but my Shire Head Piece as well. I was reading the items in the bubbles that popped up looking for Shire. It didn't because it took too long to load. So, it was saying I was still on my Ninja helmet when I was on my Shire helmet. That is the bug I wish to report. Please, please, compensate me for my Shire Dark Knight helmet.

Shire Gear can't be sold or traded in at the moment...

You can only throw it away and for this you have to check a checkbox in an extra dialouge window, if you didn't deactivate it.

OP, since the Shire gear can't be turned in for GC seals yet, you should try typing "/isearch shire" in-game (without the quotation marks). This will search all your storage/inventory/retainers for any item with the word "Shire" in it. If the helm shows up in the list of results, in the chat log, right click it, and click search for item. This should show exactly where it's hiding.

Tip for preventing stuff like this: there's a field on the GC turn in page where you can filter it to not show gear used in a gear set. So you can't sell those by mistake.
As for your current problem, people already said it, the shire gear can't be traded in yet, so either you threw it away or it's somewhere.
