This happened once and the item in question was an 'Empyrean Shrine' tabletop item, I placed it on the floor in layout mode, and when I exited it disappeared. It was no longer even listed in the list of furnishings under the 'placed' or 'storeroom' tab, just completely gone.

Just to get some common questions out of the way,

• I did not accidentally discard it, or move it to some other zone like my inventory.
• It did not warp to somewhere out of my sight, nor do I believe this to be related to interactable item culling (as I mentioned, it no longer even exists in the list of furnishings).
• I was not using the 'Preview Indoor Furnishings' function, it was a real item.
• No one else could have removed it, I am the only owner of this house and it happened instantly.
• I have tried relogging and re-entering the house but it has not reappeared.
• I was not using any 3rd party tools at the time.

Frankly I'm quite stumped, I've been decorating houses for years and have never encountered anything like this. I've not been able to replicate this bug with other items, and I don't have duplicates of the item to test it. I'm not quite sure how you would even go about verifying this report since it might be a one-off thing specific to the layout of my house in particular, but maybe there are server side logs that can shed some light on what happened or something.
