Retrieving item information bug

Hi, i got problem with my Meteorite Crystal trinket, my game cant load it somehow, but item is in my inventory, i can equip it, i get intellect stats from it but i can't activate it. It says "Retrieving item information" when i mouse over it. I tried unstucking my character, deleting my error and cache folders but nothing helps. This is not first time this is happening to me, and every time same item, meteorite crystal. Last time i fixed it by unstucking character on site, this time it doesn't work. If anyone knows how to fix this problem i would be really thankful.

Well sometimes it does appear yes, what you can do is just relog. Teleport to like Darnassus with not many people and wait 10-15 minutes (let it be in bags) and should work.

Not working, i've been waiting for like 30 mins and nothing. Other players can see my item in trade window but i can't..

Can you disable addons for a moment and see if that works? I know sometimes it happened for me aswell, but after /reload or simply waiting for mins it worked. As for why it happens, well there can be various reasons, but most common ones are out of date addons or it simply bugs out. If disabling addons and /reload doesn't work, you can try to make in-game ticket and ask if it's possible to replace this item to see if that fixes it (I am not sure about the policy of that tho). But first let me know how it works out now and perhaps we can work out something.

Yes disabling addons worked... Idk what addon may bug that, but thanks for help :)

Well, anything that can modify your bags, or items I would say.
