Bug/Issue Massive Dupe with storage locker.

Okay, So while playing on my friends single player game that we had joined, we have stumbled upon a HUGE glitch.

We have found that sometimes, if you have stackable items (minimum of 2), put them in your storage container, then put a single one in your own inventory.

Then, with a simple Shift+L click, You Itmes magically become a full stack!

Now once we restarted the server it seemed to have fixed itself, but I figured it is something that I should post in hopes that this will get fixed in later updates~
