Issue description:

Importer/Exporter is reset

What happens:

If I have an importer or an exporter configured with a few items, and then place a Chisels & Bits cover on the block, the block is reset to having no configured items. You can configure them again after the cover is placed, but this is not ideal.

What you expected to happen:

The importer/exporter should keep its configuration when I place a multipart over it

Steps to reproduce:

1. Place down an exporter
2. Add "cobblestone" to the exporter
3. Place a Chisels & Bits cover (crafted via the bit saw) over the side of the exporter
4. The exporter's configuration is reset

Version (make sure you are on the latest version before reporting):

• Minecraft: 1.12.2
• Forge: 14.23.1.2566
• Refined Storage: 1.5.28

Does this issue occur on a server?
Unknown. I play on a single player instance.

What is your chisel and bits version? And your mcmultipart version?

Chisels and Bits: 14.11
MCMultiPart: 2.4.0

Those are the latest versions on Curseforge.

Any logs?

Nope. I watched the console window as I placed the block and there were no messages. So unless the error occurs during initialization of the mods, no logs.

This is a mcmultipart issue.
