No – you are exactly right..
My V2.0 of my database uses what I call UniqueID’s for all items (auto-increment integers)… Like, each casino has a uniqueid… each bonus has a uniqueid and is tied to the casino’s unique id.. and so on..
However, I created the slots database quite a while ago and in order to retro-fit – it would take some doing. I think it is that time because I am running into these type of issues as I add new slots to the database 
Like I said – time for V2.1
