Describe the bug
I think, Minecraft crashed, when I edited the settings of Storage Bus, that had been connected to Storage Crate from with a couple of armor pieces. I insert there the Fuzzy Card and few second ago, when I tried to sort the content of Storage Cells through the IO Port. Doing this, I wanted to extract armor from cells to Crate, but Minecraft crashed.

Additional context
Crash-report: gist

Environment

• Modpack: StoneBlock.
• Minecraft Version: 1.12.2
• AE2 Version: rv5-stable-11
• Forge Version: 14.23.4.2760

That is a really odd crash.

Any additional info? Like which mod does provide the inventory? Can you reproduce it in a new instance with just AE2 and that particular mod? Items stored, one time crash, etc.

I just tried with new verison, all is fine.

I kinda doubt that a version update would actually resolve it, but it was most likely just a one time crash as it is a pretty obscure one.
