Here is a screenshot:My cook has 2 zones around him one for meat, one for vegs. I m trying to feed these zones from the stockpiles setup on the adjacent rooms.Since the belt only takes what is directly on it i made a lot of belts on the vegs room to the left.What i believe happen is- something gets picked up by one of the vertical belts, when it reaches the queue, since it is in a zone it gets teleported out of its position at a random spot in the stockpile. That s one thing and i understand the logic eventhought aht s not what i would want to happen.- as it lands at its new position it is free to use and keep moving and remain free to use untill it reaches it s destination or another beltHere are 4 sequential screenshot to show what i mean, the pile of potatoes keeps jumping like this (screens are taken like 1 sec apart):Note that the 2 piles of rice which are marked as do not use, keeps swapping position too. The one which isnt marked as do not use doesnt move. And i suppose it s here because it s been teleported through the same process and thus will remain untagged like the one in the kitchen.I hope my explanation is clear otherwise i ll try to make a video.Thank you
