For some days,
I have created a very steep map from height map, for playing and demand of Japanese community.
When I was going to build bridge at deep ravine, the simutrans returned error "bridge is too high for its type!".
I changed the executable. It based 120.1.3.
Change "bridge_reader.cc" line 143, "besch->max_height = 7" to besch->max_height = 31".
Well, I can build the bridge, but the pillar is drowing only seven heights.
I reed source code, but I don't found a reason. Why don't draw?
