There is a "maximize height levels" option in "Load Height Map" dialog. What does it do?
I see no difference with my heightmaps.

That should be from this:
Allow load height map with high mountains (https://forum.simutrans.com/index.php/topic,14919.0.html)
Thanks.
My impression is this is an obsolete setting.
