Cannot place a sofa

Hiya, sorry this is probably in the wrong place but I'm not sure how to start a thread or ask and this is working so i'm gonna put my question here if that's okay. If not then please direct me in the right place to do so. I'm new to creating and have recently made a small collection of 90's inspired bubble chairs. Now I want to add a sofa to that collection. I had seen there was another creator who made some but they were for TS2 I think. Mine are minor tweaks of EA's mesh. I took those awful twin peaks off the HSY's chair, rounded it off a bit, and added transparency. The chairs work fine. When it comes to the sofa obviously I had to change the rigging and tuning. I cloned the bubble chair and gave it the tuning for object_sitsofa3x1_EP12GEN. For rigging I gave it _universalTransition_slot_12 because it's the same as the sofa from HSY. I edited the mesh and imported all LODS. Everything went well. I loaded up the game and it was in the correct place with the correct thumbnail etc etc but when actually trying to place the object it won't place. The sofa is there and visible but it won't place.  I have better exceptions installed and it didn't throw up any errors at me. There's no weird question mark over it. It's not black or blank. It just simply won't place? I thought maybe it was because the footprint hadn't been adjusted so I adjusted that to fit and it hasn't made a difference. Somebody please help!!!
