I use Ark Advance on my server, and just recently picked up your mod. However, I have run into a problem.

Apparently the sorting box does not register the wood and stone storage racks from Ark Advance. I had a wood storage setup, in range of the box, with a single stack of wood inside it, and when I placed a dozen stacks of wood into the sorting box, it spit them out onto the ground.

I'm guessing it has to do with the unique nature of the wood and stone storage racks. Perhaps this is something you could add to your mod in the future?
