Expected Behavior

Not to crash

Actual Behavior

Hovering over the Blueprint Book causes a client crash. Also, interacting with storage (chests, barrels) with Blueprint Book in hotbar results in same crash.

Looks like this issue is similar to #218 , except that I am playing Minecraft 1.15.2.

Steps to Reproduce the Problem

1. Have Blueprint Book nearly 3/4 full of blueprints.
2. Hover over book or interact with barrels/chests.

Does this happen without Optifine?

If this is the same bug, it's caused by Ctrl+clicking a slot in the player's inventory, which causes the selected slot index to go out of bounds. Editing the book's NBT to set the selected slot to a valid number (like 0) is one possible workaround.

I edited the book's NBT and am able to enter the world and interact with chests and barrels etc. I have not yet tried to reproduce the problem without Optifine.
