Mythic item disappeared after attempting to store it in a full cache

Around 8PM PST last night, (2/23/26), my wife & I just completed a Treasure Breach where I obtained 2 Harelquin Crest items. As soon as I got back to my home town in Kurast, I attempted to store the items into my stash. I hadn’t realized the cache was full and received no warning. It just let me “store” the item and it was gone. I checked every other cache tab I had to ensure it hadn’t been moved. I exited the game and logged out twice, hoping it’d show up in my stash upon restarting, but no luck.

I showed my wife that the game would continue to let me “store” items in this cache by clicking “store” on a junk item and then transferring it to the full cache and sure enough, that item would disappear as well.

I moved more than 10 items from the full cache into another cache, hoping my Mythic would reappear somehow, but it didn’t. I know I’m extremely lucky to have obtained two and I likely wouldn’t have even reported it, but the GA of my existing Shako is on armor and I’m 10k over-capped as it is.
