Trucks will not acknowledge new areas of dump zone after current zones are full. They will only do so if you remove the storage then reapply it to the same area.

That’s normal. What else should they do? You have to make a new dump zone.
I have not experienced that. As soon as I add new designations or move the tower area they are being directed by, they go right back to dumping.
Not sure I follow what the issue is, could you provide a save file and a bit more explanation?
Old dump zone was directly under the highlighted truck and was finished. Applied new zone as seen in the screenshot. These trucks would just sit where they are indefinitely until I removed the looses storage they had filled from the export to this tower and then reapplied it to the same tower. They then began to fill the dump area again. This has happened several times. It seems to only happen when the dump zone in fully filled within a towers designation.
Seems to be with Rock. Don't have the issue with dirt only.
