In Pineline Bay, after completing the contracts "Power lines 1, 2 and 3", the crafting zone at each locations does not stay saved as an infinite cargo warehouse.
If we complete those contracts, and reload our save, the infinite cargo warehouse dissapear and the crafting zone comes back.
The zone after completing "Power lines 1"
The zone after reloading my save, the crafting zone is back.
For the "Cabin workers production" zone, after completing "Power Lines 2" it changes to a warehouse with infinite supply
But after reloading my save it changed back to a crafting zone
And same thing for the Concrete batching plant, revert back to a crafting zone after a save reload
