Hello!
Thank you for bringing this mod to 1.12.2!
I would like to get this mod into my current modpack but am having issues with it and Simple Storage network (https://minecraft.curseforge.com/projects/simple-storage-network).

Fist things first, the Storage Link cables do not connect to the reinforced chest, nor any version of the storage lockers. Storage link cables do connect to the storage crate.

However this brings me to the second issue. If the Simple Storage Network is connected to a multi block crate, I get this crash when attempting to access the Network.

Forge:14.23.4.2760.
Simple Storage Network: 1.4.0
Better Storage Too:3.0.0.0

Out of my own curiosity I tested it with Refined Storage. Same issues occurred. External Storage did not properly interact with lockers and reinforced chests. And I received this crash when I put an External Storage Bus on a multiblock crate. https://pastebin.com/5yqsdgxz

Forge:14.23.4.2760.
Refined Storage: 1.6.5
Better Storage Too:3.0.0.0

Should be fixed now.

Thank you!
