Objects dissappearing

Hi ! 

So i search for about 3 weeks before explaining my problem . I don't usually, I always find a solution because someone had that problem before me , but I didnt find my specific problem here . 

So I recently started playing with mods. Those are the TOOL mod , BBB ( betterbuildbuy) and the red shelf . 

For 2 weeks everything was fine until some objects disappeared. Those objects were moslty shelves or decorating objects ( like those wood statue your sims can make which I found in debug ) 

I should also say that it's was always the same shelves , I replaced those and when I would exit the game and come back the next day those same shelves were gone. 

It's was 2 cube shelves in the living room and 2 wood statue  , then 1 shelf and 2 wood statue but it's still disappeared.  

All of this was with no sims in the house , I was building a house. So the eco lifestyle pack isn't the problem. 

I repaired the game, deleted all the mods except the red shef. So when I did that , the shelves that would continually dissappear stopped but now it's was another shelf in the kitchen that started dissapering again and again . Btw those shelves were from the home decorating pack . 

So I thought maybe it's the MOO cheat ( never happened to me before but I read it did for people ) because that shelf in the kitchen was place with MOO . 

BUT then it wouldn't make sense cuz those cube shelves in the living room weren't place with MOO but still disappeared.  

So I closed the game  , repaired it a second time , and magically its was ok .  

I still check everytime I go in the game but so far nothing.  

I'd like to say that i have the game since its release , and that never happened to me . 

So is there anyone who could tell me the reason ? Cuz I would like to play with those mod , and I don't why I can't when I know so many people use it without problems ^-^

Sorry for the long message but I'm kinda new to asking people help on forum ^-^'
