Items that are dropped by removing the structure/object they are attached/resting on

Would like them to also be dropped in the loot bags, rather than disappearing.
things like torches attached to walls, flagons on tables, etc.

At the very least, some sort of “alert - [target] is supporting other objects. Are you sure you want to remove/destroy?” message. (and for this to be an optional checkbox in settings)

Good Idea.
Or give us at least the Mats from that wall that is attached to the wall you destroy. It would be logical.
