Issue description
When I build conveyor belts (red construction/rubber) or retaining walls (iron/concrete sheets) the trucks only deliver one of the two items, which ever gets there first. Then the second item does not get delivered. I have to use unity to finish them. Just noticed it after last hotfix. Please fix. Thank You.
