Since patch 8.1.5 there are some items that are not showing in bags when looted as well as items on other characters no longer showing up when mouseovered.

Items disapear from my bags unless I turn the addon off, once I turn it back on, it just selects random items to act as if they are not there.

I'm plainly just having items not showing, my Twinblades of the Deciever & Aluneth (both artifacts) are not showing, nor are the (legendary) Warglaives of Azzinoth..

This is still an issue in 8.2, as of 06 Jul. I loot items and they do not appear in my bags, if i disable the addon they reappear. This happens when looting and crafting, I was trying to make space by making 200+ bolts of windwool, after 200 they would and act like I had them but they were not visible in the bag.

Disregard, I found my problem.

I inadvertently unselected a bag
