Item dupe with exporters

[Burkino]

Describe the bug

By setting exact mode to off with exporters you are able to override NBT data with an existing item, there are tons of containers that can hold an item, thus creating duped items.

How can we reproduce this bug or crash?

1. Place any container (with 2+ slots) such as a chest
2. Place a storage bus on the same chest
3. Place an exporter on the chest
4. Add stack upgrade(s) to the exporter, set exact mode to off
5. Export any stackable container that can store items (storage drawer, bee cage, etc)
6. Put the item you want to dupe in the container, place it in the 1st slot of the chest
7. Put more of that container in the chest, they will copy the data of the 1st slot
