Supposedly if you right click the lunch box in your inventory it will add items into it automatically, it doesn't seem to be working for me.

If you right click on an inventory in the world (like a chest) with the lunch box in your hand, it will add items from the chest into the lunch box.

oh! awesome, thanks!! :)

although... I just tried it on 6 64 stacks of different foods... and all of them got added to the lunch box, but the 64 stacks all disappeared, essentially deleting a lot of the items.

Didn't realize you opened a new issue. Moving this discussion to #123

heh sorry, figured it should've been seperate as it in itself was a bug
