While we're talking about furniture and layering, the floating red & white tire thing (that was sold at Nexus some time ago, and you can see in Oasis, although not purchase) has this issue where it automatically defaults to layer 1 (which screws it up since all chair-type items need to be set to layer 0 otherwise they appear on top of the character). I switch it to layer 0, but when I enter my house and come back out, it goes back to layer 1.
The heart pot furniture item has a similar problem (except it reverts back to the first layer the moment you de-select it), although I'm thinking this might be intentional. If it is, it would be nice if you guys could just remove the layer option from this piece of furniture.
