whenever i place an Item in my slot, it wont place it down, but place a copy of it. so i have two items. and when i want to take it out, it just disapears !

 

Everything is working fine, and its the last thing I need for it to complete !

 

Here are a few files you might want to take a look at if you want to help me

I'm pretty sure it's just a matter of a line.

Server and Client are out of Sync, thats what I think, but dont know where
