I need to find a way to keep track of the enderpearl stack so I don't run into board linking issue. Basically, board1 and board2 can link properly, but if I place board3 and board4, they will link to board1, assumption that this is the cause of this problem is that board3 and board4 are linking to the nbt of board1. I drew something to help me visualize the problem.

that makes sense, I did enjoy playing with the NBTs tho :)
I will push to anew branch just to show you what I did exactly

potential solution:
Adding a custom NBT tag within the chessboard block entity itself, also gotta clear the stored data so we can create another link. Will this cause issues with the first linking? gonna find out this afternoon :))

my bad I meant QuantumChessBoardEntity. creating an item might make it more chaotic, no? I think we add a chessboardID to the nbt of the quantum chessboard so we can check the IDs before linking

I'm almost done I'll finish testing and push to a new branch so you can review
