Missing Dams In Portugal / FTX Vector Temporary fix.
After some investigation I got the dams to appear in the scenario
The problem is in the ORBX! VECTOR_EXX file. By moving the file in the hierarchy of the P3VV4 scenario, placing it below the file "0501 base " The dams appear. It's not perfect but it's better as it can be seen in the image.
The problem appears to be in the ORBX! VECTOR_EXX that eliminates the dams!
I hope you helped and that the problem is definitely solved!
