Building Gadgets Version
1.3.9

Describe the bug
After anchoring a block with water underneath it, the copy/paste gadget and exchange gadget will create/replace blocks without subtracting them from your inventory if you have the replacement blocks inside of a Sophisticated Backpacks backpack.

To Reproduce
Copy/anchor a block with water underneath it. Paste/replace the block. No blocks are subtracted from inventory or backpack, as long as any of the supply blocks are inside backpack. Even if the GUI displays red blocks (because you don't have enough), it will place all of them.

Expected behavior
Blocks should be subtracted from backpack or inventory, or fail to paste/replace.

Edit - tested this with a vanilla as well as sophisticated / upgraded shulk box. No issues there, blocks were correctly subtracted when inside the shulk box (if the supply block is not also present in my backpack.)

Screenshots
Duped 9 netherite blocks.
