❗ Checklist

• I am using the official english version of Slimefun and did not modify the jar.
• I am using an up to date "DEV" (not "RC") version of Slimefun.
• I am aware that issues related to Slimefun addons need to be reported on their bug trackers and not here.
• I searched for similar open issues and could not find an existing bug report on this.

📍 Description

If you connect two chests via Cargo Nodes, you can copy metadata of signed books and player heads from one to another, resulting in, for example, duplication of "cheque" books, or other valuable books or heads.

📑 Reproduction Steps

1. Have two signed books (A and B).
2. Place these blocks (listed from left to right, but placement order does not matter, appaerently):
   • Chest,
   • Cargo Node (Input),
   • Cargo Manager
   • Cargo Node (Output),
   • Chest.
3. Set the Cargo Node (Input) type to Blacklist.
4. Insert the book to be copied (A) into the right (output) chest.
5. Insert the other book (B) into the left (input) chest.
6. In the right chest you will have the copied book (A) two times.

The same applies to player heads.

Also it works for higher quantities of items: for example, if you were to fill the right chest with the A books, and then proceed to insert some B books into the left chest, the item stacks in the right chest will all get eventually filled up.

On the other hand, if you would only have 1 A book in the right chest and you were to put 17 B books into the left chest, you would end up with 16 A books and 2 B books in the right chest. So the issue is clearly linked to incomplete item stacks.

💡 Expected Behavior

I would expect the B book to transfer to the right (output) chest, instead of getting another A book.
