So now that there's an option of buying multiple items at once, there's a number at top right that shows how many items you can hold in your inventory (that's what I assume, and max is 60)
So what if you put more than 60 items in your inventory by restoring? What happens
Second of all, it said I have 6 items in my inventory, however I had 5.
After removing them, one was left and no furniture I my inventory. Why is it so?

Thanks  

It includes the furniture you are attempting to buy, so it will include the one furniture you're you're looking at when buying(So in this case, 5 you own + 1 you're looking at). Also nothing happens when you go over 60, you don't lose furniture you just won't be able to buy anymore.
