Don't be too excited, due how the current item system works, I had to haxx some, and if you have 2 or less items, it wont work as expected. The result is that you cannot scroll as normally. A temporary fix for this is when you have one item, it will only scroll up in the inventory even if you scroll down. When having two items you can scroll down as normally, but you cannot scroll further than one item down, then it will scroll up. If something gets jacked(Probably it wont) you have to use one of the commands /MoveInvUp or /MoveInvDown to move in the inventory until it finds next valid item.
You'll probably understand when you try it out. I'll see if it can be today, or on an another persons server tomorrow. I am no good when making TDM's...
