Items on 2nd floor visible from ground floor?

[amg31490]

I'm having a glitchy day today I guess 

So I have an ice cream statue from the Sweet Treats expansion in my arcade room on the 2nd floor. For some reason, when I am viewing the ground floor, I can see the statue just sort of hovering in the air. No other items can be seen from the 1st floor. Just the ice cream statue.

I didn't use moveobjects or anything like that when I built my house. What could possibly be causing this?
