Download Samebridges.zip for the files. Play with it and see if you get the same results!
For the good bridge, the truck always makes it across regardless of the timing. For the bad bridge, the truck sometimes makes it across, but never if started immediately (using pause/restart/test/unpause) or if started after 20 seconds.
What's going on?!? The bridges look exactly the same!! Please help me understand the difference here. Thanks!
However, my question remains: why do the bridges act differently, even though they are the same in construction, same price, everything?
I didn't copy the file, and I discovered this by accident: I was playing with the bridge, and copied the entire bridge off to one side to try something different. When I copied it back, it didn't work anymore, even though all the links where there and the price was the same. I am just using the copy/paste functions inside Pontifex II.
Argh! It feels like this program has something wrong with vehicles passing over bridges that I can't control with construction.
