Removing mod did the trick
I got around to removing an old mod that was causing the City to have major graphical issues every time a ferry system was put down in San Solarian City.
Given the City sits on a coast line and has a river running through the middle of it the ferry system I thought would be a novel to set up a basic system that travels both the coast and river system.
At the moment I have only established the coastal system with ferries running between the Port District and Wood Hills with stops along the Downtown and City Centre waterfront areas. So far most of the users of this ferry route are tourists (go figure) rather than commuters. I will later today establish the River to Downtown Ferry route and see if I can get a few commuters there.
In the meantime here is the first ever ferry system – in San Solaria City
