[0.16.27] Cliff not rendered depending on grid alignment

[blueblue]

I am creating cliffs with south-to-none orientation via console command and with some y coordinates the cliffs will come out invisible, e.g. at (10, 1) and (10, 3) they will be invisible while at 0 and 2 they will be rendered. No mods used.

Thanks for the report.
Cliffs need to be aligned larger grid than normal (similar to how rails need to be aligned to 2x2 grid).
For next release I fixed it so it snaps to proper position.

If they're aligned to a 4 by 4 grid now, then i'll have to redo part of the map for my scenario. 4 by 4 alignment is super strict, it only allows for certain ramp sizes for example. Another example is something like this which is really useful to separate certain areas from each other. I admit it does make them easier to handle in general but I dont like it.
