TTDPatch 2.0.1 alpha 63 or later
Configuration file: autoslope on|off|<cost>
Command line: N/A
Normally, it is not possible to raise or lower land on which for example rail tracks have been built. With this switch, it becomes possible to do this, and it will automatically add or remove foundations as possible. The only limitation is that the new land shape must be suitable for the objects that are built on the tile, i.e. the foundations must be possible to build for the new shape.
<cost> may be 1(default), 2, or 3, and is the cost multiplier.
