store box ain't existing

I don't know if this topic must be here or in bugs section
The topic is about, in my property that i don't have other properties than it before i buy it i was rob it a lot
But when i was rob it there was a box for store money/weapons in it an now when i bought it, i can't find this box in it again like when i was rob it.
You have to buy that store box for your house its called safe. When you enter your house press H then there is option to upgrade house like insurance, safe(store box) and dont know really what was the third option so yeah its not a bug.
