What happens:

Use bound shovel near botania flowers, and they lose all NBT data on drop.

What you expected to happen:

NBT data properly retained on drop

Steps to reproduce:

1. Setup botania magical flower or floating flower
2. Use bound shovel
3. Observe drops

Code analysis

In the shovel[1], You are using a hashmultiset of ItemStackWrapper, counting how many of each occur. However, the factory method that creates these wrappers completely ignores the NBT of the stack that is passed in[2], leading to any drops getting their NBT data completely wiped.

This issue may also be present in other places that use this class that I"m not aware of.
