Station rating never goes above 40%
Multiple stations I have will never go above 40% even though there's 0 cargo waiting, always a train or plane waiting to load cargo, with a statue in the nearby town and is very well serviced with fast vehicles.
It's affected by either OpenGFX+ Trains 0.3.0, OpenGFX+ Industries 0.3.5, OpenGFX+ Road Vehicles 0.4.1 or OpenGFX+ Airports 0.4.2, or any combination of the four.
I removed all 4 newGRF's using scenario_developer true, and the rating shot up to 80%+.
Savegame is attached, it's focused on the main culprit station (Marnbridge South).
