can't find red bug box

[Gesundheit]

I have a sim collecting insects. I get messages saying she continues to find different ones, but the box for holding them seems to have gone missing and isn't in her inventory. How do I find it? Is there a way to re-spawn it?

Perhaps you placed it somewhere on the lot?

The sim is living on a residential lot at university. It isn't at her childhood home and I think I may have accidentally deleted it along with a wall when I was remodeling. If I did delete it, how would I get it back?
