Mod version:
HoloInventory: 151
StorageNetwork: (really doesn't matter, did it with multiple versions)
Forge version: 2811
Minecraft: 1.12.2

While attempting to place connectors together, plain cable or otherwise, from the StorageNetwork mod, instantly kicked with the message about Fatal Error. Sadly, no logs reported a crash.

Just to let you know, I did figure out how to fix the issue but thought you might want to fix it so a non-compatible mod doesn't kick the player every time.

The fix, of course, is to use the commands that are part of the mod. But I didn't learn that until today (by poking around...)
