Not enough inventory slots

So the kit has more slots than can be filled in players inventory, So players do not get all Items in the kit, 
 I did find a way to get around it for now, by adding some items in the backpack an letting them know some are there, 
But this really needs some kind of fix where they can empty their inventory an then go back an get remaining items, 
 Not sure how that can be done without them getting all items again .
