Fair warning, not 100% on how to duplicate this.

I had a crafting star (an array of interfaces and molecular assemblers that takes 16 channels) suddenly go offline and say that it was only using 4 channels. After breaking half of it down, I noticed that both the Assemblers and Interfaces have additional NBT data when they normally have none.

After swapping them out for ones without NBT data, system comes back up to normal and says that all 16 channels of the star are in use.

This occurred on the server and I will keep one of each with NBT data aside if they need to be looked at later.

Images of the bork'd star and of an Interface showing weird NBT below.

NBT of one straight from JEI:

[08:13:05] [Client thread/INFO] [mcjtylib_ng]: ### Client side ###
[08:13:05] [Client thread/INFO] [mcjtylib_ng]: {
"item": "appliedenergistics2:interface",
"meta": 0
}

NBT of one that's glitched out:
[08:13:06] [Client thread/INFO] [mcjtylib_ng]: ### Client side ###
[08:13:06] [Client thread/INFO] [mcjtylib_ng]: {
"item": "appliedenergistics2:interface",
"meta": 0,
"nbt": [
"BLOCK",
"priority",
"config",
"INTERFACE_TERMINAL"
]
}
