Found that while the chunk claiming for another player's base was working (couldn't access chests/RS grid), I was able to open up their Reborn Storage crafting multiblock and take/move patterns inside.

Discovered in the Sky Factory 3 modpack, version 3.0.8, for MC 1.10.2

Willing to test mods in standalone environment if necessary.

Yeah this is because its not handled like a normal TileEntity as its a muliblock there is not alot we can do about this

I think I have an idea why it's not working.

Draconic Evolution energy storage cores and Extreme Reactors..reactors...are properly inaccessible, and I'm 90% sure they use multiblock code

I dont think is something I can fix. Come back if im wrong.
