Hey! Im trying to find a way to automate the production of fish but i dont want my cranes to carry my items even when the container is full, so i made this loop to endlessly carry peppers until a spot is free, but it causes a lot of lag and it feels realy unoptimal, is there a way to make the crane either only drop the correct amount in the containers and/or only make them move items when a spot is free in the container? thx
