Bug description

When swapping items certain items out in the enchantment table (specifically ones that can be enchanted with multiple types of materials), the game can have a rendering error and crash. I suspect this is because the lists the code uses to determine what item previews in that slot are different lengths. For example, the preview is displaying item number 2 on a 3 item long list. You swap the items so that the preview list changes from 3 items long to 1 item long. It tries to find item number 2, fails to render it (because it doesn't exist) and then crashes.

Steps to reproduce

1. Get the following items
   • An enchantable wooden or stone item. In the video I used a stone item, but it is easier to reproduce with a wooden one.
   • Another enchantable item that isn't one of the types listed above. I used a diamond item.
2. Place the wooden/stone item in the enchantment table. Take note of the slot that shows what materials can be but into it.
3. Wait for the material preview to change items, then swap the two items in the enchantment slot by clicking. (See video, 0:21)
4. Crash
