The most recent nightly seems to have messed up passenger numbers. From my lines running near 100% capacity they now run near 0% capacity. In fact generating passengers at all is extremely hard now. From over 4,000 passengers per month at some docks they are now hitting a massive 150.
In fact most towns now say they have produced 0 passengers (attempted trips, the potential passenger generation for a city) in total all month. Something is really VERY broken now, passengers are not being generated at all.
I have split this from the other post as this is an entirely unrelated issue. I am currently investigating.
Edit: I think that I have identified the problem and I have just pushed a fix to the Github repository.
