I'm unsure if the issue is with the item crafter or if the itemJuntion is to blaim ...
Reproduction:
ItemCrafter is connected to a back to back item junctions Container can be double or single connected to the other junction.
Variance:
Depending on the how the container and itemcrafter is connected, different results occur. After save and reload of the game, different experiences can be seen.
If the ItemCrafter input and output are both connected to one side of the "Back to Back" item splitters ... the itemCrafter works better, but still is unreliable.
