The luggage picks up mana beans of two different types then stacks them together based on the first one in the stack. For example I place the luggage then drop an Auram mana bean. It picks it up and places the bean in the first slot. I then drop an Ignis mana bean. The luggage picks it up but instead of placing the Ignis mana bean in the second slot it adds to the mana bean count in the first slot, so I now have two Auram mana beans in the luggage. Once the first stack is full the next mana bean type picked up will determine what the the next stack of mana beans will be. I would assume any other items storing data in the same way as mana beans would also be affected in a similar manner. I am using the current Direwolf20 modpack if it makes a difference.

We fixed few things in library. Should be solved now.
