WHY does THIS work?
What is happening is that the script puts 4 items on sale in the marketplace, But it doesn't put its full value so what it does
sets it to a decimal 3.1-3.3  meaning there is 3 and a bit items, the game does not recognize that and thinks it's 4 items, but you still have 0.7-9 item in your inventory?
This means that when you drop it the 0.7 it's still an item meaning it will drop the full item because there is something still there!
Once you dropped it in the chest, it won't add onto the old value for example 3.1 in the store 0.9 inventory making 4 but what will happen is 3.1 when you are dropping it you will end up at the last one with 0.1 even though it's not a full value it will still give you the bag since there is still something there.. meaning it will drop 4 items from marketplace even though you put 3.1 and 1 items from 0.7 = 5 items :D
