I have an update to my saga...
After 3-days of restoring my install, replacing and deleting content that had missing dependencies or were faulty and really, really old and not used in ages, I finally tried the new update.
I noticed that the program is faster, the computer runs cooler and nothing is amiss. To test Driver I ran my complex Gloucester Terminal Electric route with lots of light rail trams running all over the place and the session worked fine.
I did see something off but I'm not sure if this was always the case. Stations don't disgorge passengers when the passenger-enabled trams pull into them. I'm not sure if the trams are bad and always were or this is a bug. I need to investigate further. Other than that, Surveyor works fine with track bending the way it should, signals attaching to tracks and everything else going as planned.
