I was playing my world with Project Ozone 3 mod and I have a Crafting Station next to a Bag Opener. In the crafting station, i can see the "storage" from the bag opener where the first slots are the top slots from the bag opener. I discovered that if I put an item on the crafting station, and I search another craft on the JEI and put the recipe automatically in the crafting station, the item I had before is placed on the bag opener and it starts to create that item infinitely. I tried some items and it seems like works with everything.
I imagine it is a bug between these two mods.
