[2020] Oil route crossing pirate cove

Any oil tanker built in the old world and assigned to a route originating in the new world will consistently enter the new world EXATCLY in the pirate cove, causing to be destroyed even with escort. I tried moving the destination in the old world to another island, but it will still enter the new world in that place. What can be done to avoid this highly frustrating bug? Shouldn't all boats traveling from a region to another enter anywhere except there?

Thanks in advance for the input.
