Good morning,
I asked a GM and they were unable to help me retrieve the item.
I accidentally clicked a Felsteel Cage somewhere out of bounds in my house, and the GM said they were able to see it, but on my end it was clipped out of bounds and invisible. It does not appear in the list of objects in my house and I have no way of retrieving it. The GM was not able to give the item back to me.
They suggested that I make a bug report, hopefully the housing devs give us a way to retrieve items like this. Thanks
