Steps to reproduce [If Applicable]

So here's what I was trying to do. I was feeding buckets of water into a chest, the auto workbench section would pull them into it's storage and convert the water bucket into "Fresh water" for Pam's Harvest Craft (In the end, I want to be able to craft a bunch of Pam's stuff but I suspect there's going to be lots of issues due to the way this auto crafter works). An empty bucket would get put back into the auto crafting storage. For the life of me, I have been unable to figure out how to to get those empty buckets back out of there so I can refill them. So I was trying out a variety of filters. The last thing I tried was to add a chest to the "west" of the auto crafting. Placed an empty bucket in as a white list filter, and when I went to enable the chest storage for input, it crashed.

Couple things. I use custom mod packs and so, since my go to mod Buildcraft isn't available for 1.10, I've been looking for an auto crafting table. This is the second time I've tried this one (previous version was 1.3.6 which ended up crashing a lot) and so was hoping this newer version would be ok to go. I like the idea of what you have here but there's some irksome things about it. The main one is that you have to put usable items into the crafting table instead of just filling it with a pattern like all other auto crafters I've used. This leads to problems. It would be much better if you changed it to be a pattern and people have to fill the storage (or it pulls automatically from external storage) in order to craft. The empty bucket thing is also an issue or maybe I'm just brain dead and can't figure out how to get them out.

Anyway, as I said, I like the idea of what you've developed and I hope you carry on improving it.
