Hi,

I'm not sure what's causing this issue, and I have not managed to reproduce it intentionally. But it has happened in several different worlds with several people, and I'm hoping someone else maybe have seen this and can share some thoughts and maybe pinpoint the issue.
My current world do have this issue.

I often make systems for sorting items, and I place rows of double chests with every other chest being a Quark chest(or all of them in different wood types).
When using the smart deposit button by holding shift and clicking the blue arrow from inventory, items does not always getting sorted correctly. Some items do get sorted correctly, but some is getting mixed with other items, even if the chests does not originally hold this type of item(yes I'm holding the shift-key, the arrow is blue).

From what I have tested in my current world, it seems like items I have in my inventory, that exists in chest to the left of me, get randomly "sorted" in chests to the right of me. But items I have that exists in chest to the right of me, get sorted correctly.
That happens both in front of me, and behind me.

First I thought it was some random wierd bug in my world/my setup of some sort, but now I've seen this exact issue in three or four different servers I have set up.

Right now I'm playing with forge 12.18.2.2103 with quark 1.0-56, but in earlier servers I've used earlier versons with the same issue.
I do have a lot of other mods, but none that do anything to chests from what I know of.

It does not happen all the time, but if it suddenly happens in one setup, it persists.
If I for example remove chest number two in a row of chests, so that the first chest is sitting there alone, it suddenly works fine for items that exists in that chest. So it seems to have something to do with chests that is adjacent to each other.
I'm using double chests, with the long side against each other.

Hopefully someone understands my explanation of the problem :P

I think it's relevant/similar to #176.
