Describe the bug

When trying to make a setup where the pattern grid will automatically replenish patterns by using an exporter, nothing actually gets exported to the pattern grid. Exporting to a regular chest works fine.

Going back and testing this in Minecraft 1.20.1, using Forge 47.2.21 and Refined Storage 1.12.4, things work as expected.

Edit to add: Using NeoForge 47.1.103 with Minecraft 1.20.1 also works with mod version 1.12.4.

How can we reproduce this bug or crash?

1. Create a Minecraft instance using game version 1.20.4 and NeoForge 20.4.218
2. Install Refined Storage
3. Start a new world
4. Make a basic RS setup
5. Make an exporter to export patterns to a pattern grid
6. Place some patterns in storage
