Before a normal trade route would be go through to the loading spot, BAM back to Capital.
Now it is the opposite. Teleport to Production Outpost, and then decide if you haul it or you contract delivery to Free Outpost and then haul it.
My understanding and advice is that instead of focusing on how it was until now it is better to rethink the outpost layout and trade routes. Not because of raiders, which seem to be the prime concern here, but because of how you traders and crafters can optimize your output of materials and ship building.
The raiding of trade lanes is a given, after all it was a primary war effort of all nations in the age of sail if not the most important actually.
