Repro steps:

1. Launch Minecraft with Forge, Simple Storage Network, and Compact Storage
2. Via Creative/Survival, obtain any Compact Chest
3. Connect it to the Simple Storage Network system with the item import cable

Results:
Simple Storage Network does not recognize the storage, stopping the player from using it as storage

Additional Notes:

• Compact Storage will connect to Simple Storage after connecting the cables and then exiting and rejoining the world.
• Repro rate: 10/10
• Minecraft version: 1.20.1
• Forge version: 47.2.0
• Simple Storage Network version: 1.20.1-1.10.0
• Compact Storage version: 1.20.1-forge-6.0.1.64

I'm not managing to replicate this behaviour at all, I have

• SimpleStorageNetwork 1.10.0
• Forge 47.2.0
• CompactStorage 6.0.1.64

Bit of a necro but the issue happens only when the chests/barrels are upgraded.

also effects other inventory reading mods like tom's storage and crafting station

what version of the mod and which modloader is this?
