I've set up some crafting units in a typical configuration; A 64k Crafting Storage, A Crafting Monitor below that, and a Crafting Co-Processing Unit below that. Upon replacing the Co-Processing Units with a 64k Core Crafting Accelerator, that particular block reads as "Device Offline" while the Crafting Storage and Crafting Monitor above that read as "Device Online."

Mod Version: 1.4.1
NeoForge Version: 21.0.139-beta
Modpack - Version: Craftoria - 0.5.0

i find the issue too, but i have no idea to fix it. And this won't affect usage

Breaking the connected crafting storage and replacing it seemingly fixes it at least temporarily.
