So, i am working on a model that works like that : there is a agent (uld) coming and brings 10 items. these items are then moved by a transporter (forklift) to a particular zone. In that zone (in theory), they drop the item, wait a few seconds, and take it back and place it in a storage zone.

Originally, i wanted the forklift to not drop the item, just go in the node, wait a bit and go to the final location. I couldn’t figure out how to make it happen without releasing the item, so i let the release happen. Now, in most case, it works fine : the forklift drops the item, wait, take it back and store it. But sometimes, when too many uld are coming and drop too many items, it seems like the forklift goes straight for a new one instead of storing the item first.
Is there a way, either to make it like the items aren’t released, or is there a way that the same forklift always retake its item ?

here is the zone where the forklifts are supposed to drop and retake the item

here is the logic i used for the movement of the forklift to the zone

here is the moveby logic

here is the store logic
