This is something that needs to be addressed urgently - you know, because of the problem of getting copies of same items in more than one shop or wrong places altogether! Shops don't update but have a fairly long caching issue. Quickstocking will again and again show the same items, even though some of them have been put into shop/vault already, some were turned into humming power crystals (that's how I noticed) and the like.

Are you seeing these same items reappearing just in your Quicktock, or do you still see them in your inventory too? Because I'm running into that exact issue.

Like I tried to buy something from a shop and got them "you have to many item in your inventory" message. I turned in about 54 trinkets to make space, BUT when I tried to buy the item again, I got the same message. Tried to turn in my trinkets again and was told I had 0 on hand, but I could still see them in my inventory AND in my QS. And this is my second encounter with a slow updating inventory within the past 7 hours or so. The first being that I purchased items for a quest, but they didn't show up in my inventory.

So I'm not sure if it's QS per se or an issue with the inventory itself? I wanted to ask to see if my issue is different than yours or not.

My inventory strangely showed the correct items, respectively was empty, when quickstock still claimed to have items in the invy - quickstocking the same shop AND other shops.

However, the issue seems to be resolved for me now.

Ah, I see. I bit different than my dilemma then, but luckily mine seems to have corrected as well. Things are looking up now. :)
