Downtime delivery animation for nothing

when a Dupe goes to deliver materials to build blocks say he can carry enough for 3 blocks. he carries materials starts the first block maybe finishes not sure In any case the downtime starts either during or right after the first delivery BUT than he continues doing the animation to deliver materials to the other 2 blocks but does not actually deliver them. when the animations are done he drops the materials that were supposed to go to the other 2 blocks and than proceeds to go on break. IIt is a waste of Time that should not be. either drop the Materials and go on break or if it is going to go through the animations of delivering then it should actually deliver them.
