What happened?
On Bridgewater, a town forcefully built a bridge in a very strange way, causing a jam on Freddys railway line.
It is generally possible to force-build (ctrl-drag) a bridge to
end on a through way.
This in independant of the involved waytype as long as both involved types are either the same or there is a level crossing defined in between those types.
Such bridges do not only look ugly, but those will also cut the route of the trough way,
as just happened on bridgewater.
Another issue with this, I was not able to reproduce is a crash that can be caused by the construction of such bridges.
While building the crash setup, the game crashed twice, but I was not able to see the exact error message (the window closes immediately after showing it) nor was i able to get this reproduced.
I wll add instructions once I am able to reproduce the crash.
How to reproduce?
See the attached save, I have built any combination I could think of.
You can build any of these by
1. building the way on the ground
2. ctrl-dragging a bridge from a spare tile straight onto a flat way on the ground.
Thanks to Freddy, who noticed this behavior was not specific to towns constructing roads, but general to road construction. This made it much easier to provide a reproduction case.
